Terms of Use

Effective November 2, 2026

These terms are the agreement between you and Glassing, LLC, a Delaware limited liability company, for Glassing — the iOS app, the watch app, the web map at glassing.app, and Glassing Data at glassing.app/data. Using any of them means agreeing to these terms. If you do not agree, do not use them.

Privacy is covered separately, by the Privacy Policy, which is part of this agreement.

1. Read this part

Glassing is a map, not a guide, and not a safety device.

Glassing shows terrain, elevation, slope angle, contours, trails, land ownership, place names and street addresses drawn from public data sources. That data is incomplete, out of date in places, and wrong in places. Elevation models are approximations; slope angles computed from them are approximations of approximations; a trail on the map may not exist on the ground, and a trail on the ground may not be on the map. Coordinates and distances are as good as your phone's GPS, which degrades under canopy, in canyons, and in bad weather.

Every layer in Glassing is decision support, not a guarantee. It tells you what a data set says, with the date it says it. It does not tell you what is true today, on that slope, under that snow.

You are responsible for your own decisions in the backcountry. Do not use Glassing as your only means of navigation. Carry a map and compass and know how to use them.

Slope and terrain layers are not avalanche forecasts. They are terrain visualization. They cannot see snowpack, weather, wind loading, recent avalanche activity, or anything happening today. Consult your regional avalanche center and official land-manager information before traveling in avalanche terrain.

Land-ownership boundaries are not permission to enter. Public-lands data shows what a national data set records about ownership and management, at the accuracy that data set carries. Boundaries are approximate, parcels change hands, and an access flag in the data is a description rather than a right. It is not a legal survey, it is not a permission, and it is not a defense to trespass. Closures, permits, seasons, unit boundaries and hunting regulations are the land manager's to publish and yours to check; Glassing does not enforce them and may not reflect them.

Private parcels come from county tax rolls, and what a card says is a record, not a contact. Where Glassing draws private ground, it shows what a county assessor publishes about a taxlot: its size, its county, a published access page where one exists, and — where the roll's owner is a company — that company's name. Where the owner is a person, Glassing leaves the name out, and the parcel's own street address stands in its place. A business named after its owner still shows that name, and the filter that removes people's names isn't perfect. Rolls lag sales by months and boundaries are approximate, so the card may describe a taxlot as it was rather than as it is. It is not permission to enter, it is not an invitation, and it is not a way to find anybody.

Fire restrictions on Glassing Data are a summary, not the order. Glassing Data reads each land manager's own orders and alerts and links every rule to its source. Rules change fast in fire season, and a summary can lag or miss one. Official orders, emergency closures and posted signs always win, and Glassing Data is not a government agency. "Unknown" means no status could be published and never means campfires are allowed. Map shapes are approximate planning aids, not legal boundaries.

Hunting seasons on Glassing Data are a copy of the regulations, not the regulations. Glassing Data copies each hunt's dates, tags and bag limit from ODFW's Big Game Regulations and works out which units a hunt covers from ODFW's maps. A copy can lag a change ODFW makes, and how much of a unit a hunt covers is an estimate. Points to draw and draw odds for next year are Glassing's estimate from ODFW's last draw, not ODFW's, and the draw can come out differently. ODFW's regulations always win.

Trailhead access rules are a summary, not the rules. Glassing reads each trailhead's, wilderness's and permit's page from the Forest Service and Recreation.gov ahead of time and links every rule to its page and the day it was read. A page can change after it is read, and a summary can miss or misread a rule. "No access rules on file" does not mean none apply. The Forest Service, Recreation.gov and posted signs always win.

Campground details are a summary, not the campground's rules. Glassing reads each campground's season, fee and booking from the pages of the agency that runs it, such as the Forest Service, the National Park Service and Recreation.gov, and links every detail to its page and the day it was read. A page can change after it is read, and a summary can miss or misread a detail. "No booking on file" does not mean a campground takes no reservations. The agency that runs the campground always wins.

Sunlight and thermals are a model, not a forecast. They work out sun, shade and the air that rises and drains on a calm, clear day from the shape of the terrain. Real wind, weather and cloud are not included and override them.

Closures on the map are a copy of the order, not the order. The web map and Glassing Data draw closure orders from each land manager's own data and fire perimeters from NIFC and WFIGS, and each closure links to its order. A new copy is made twice a day, and an order can be issued, changed or lifted between copies. Some orders are not drawn at all. Ground with no closure drawn is not open for that reason. Official orders, emergency closures and posted signs always win.

Wildfire data is planning context, not a safety tool. Fire locations and sizes come from NIFC and WFIGS, update twice a day, and can be hours behind the fire. They are not an evacuation notice and not a warning system. Follow official emergency alerts and closures.

Answers to a question asked of the map can be wrong. Ask the map answers from Glassing's map data and a language model's reading of the question. It can misread a question, pick the wrong place or leave something out, and an answer carries every limit of the data behind it. Check a route, a closure, a hunt or whose land you are on with the land manager, the regulations and the signs on the ground before relying on it.

Your phone can fail. Batteries die in the cold, screens break, GPS drifts, and software has bugs. Plan for the trip you are on without it.

YOUR USE OF THIS REAL TIME ROUTE GUIDANCE APPLICATION IS AT YOUR SOLE RISK. LOCATION DATA MAY NOT BE ACCURATE.

Nothing in the app or on Glassing Data is emergency, medical, legal, fire-regulation or hunting-regulation advice.

2. Your license to use Glassing

Glassing, LLC grants you a personal, non-transferable, non-exclusive license to use Glassing on Apple-branded devices you own or control, as permitted by the App Store Terms of Service. You may not sell, rent, sublicense, or redistribute the app; reverse-engineer it except as the law allows regardless of contract; or remove attribution and license notices from map data it displays.

Glassing, LLC keeps all rights in the app itself — its code, design, cartography and brand.

3. Accounts

Glassing works fully without an account. To put your data on more than one device, create one with Sign in with Apple; that is the only sign-in offered, and an account exists for no purpose other than syncing your own data to you. The same account signs you in to the web map.

Keeping access to your Apple Account secure is yours to do, since it is the key to your Glassing account. You can delete your Glassing account from inside the app or from the web map at any time; the Privacy Policy says what that removes.

Glassing, LLC may suspend or close an account being used to attack the service or break these terms. You will be told, and where it is reasonably possible you will get a chance to take your data out first — though your data is already on your own phone, and GPX export needs nobody's help.

4. Your content stays yours

Everything you create in Glassing — waypoints, routes, tracks, trips, notes, photos — is yours. Glassing, LLC claims no ownership of it.

Signing in grants the narrow permission the service needs to run: to store, transmit and hand back your content, on your instruction, so it reaches your own devices. That permission covers nothing else. Your content is not analyzed, aggregated, published, used to train anything, or shared with anyone, unless you ask for it. Four things ask:

• A share link publishes the one record it names to anyone holding the link, until it expires or you revoke it. Making one grants Glassing, LLC permission to show that record on the share page for as long as the link lives. Section 6a says the rest.
• Importing a file on the web map sends the place names in that file, and nothing else, to a hosted model that proposes an icon for each one. The Privacy Policy says who receives them and why.
• Asking the map on glassing.app sends your question, and the names of saved items that match it, to a hosted model that chooses what the map shows. The Privacy Policy says what else goes, who receives it and why.
• Reporting an answer on glassing.app sends that conversation to Glassing, which reads it to fix the map and keeps it for up to 90 days.

The permission ends when you delete the content or the account.

What you store is yours to be responsible for — in particular, having the right to store photos you add and data you import.

5. Acceptable use

Do not use Glassing to break the law. Do not attack, overload, or attempt to gain unauthorized access to the servers or to another user's data. Do not scrape or bulk-download the map data the service serves beyond your own ordinary use of the app. Glassing Data's JSON and GeoJSON are the exception, open for reuse under section 6b; fetch them at a reasonable pace.

Do not use owner information from the map to contact, solicit, approach or harass anyone, and do not extract it from the app or the map files to build anything with.

Do not share a link to content you have no right to publish, and do not use a share link to publish where another person lives, works, hunts or camps without their consent.

6. Map data and attribution

Glassing displays data from public and open sources, including the U.S. Geological Survey, the U.S. Department of Agriculture, OpenStreetMap contributors, county assessors as compiled by Oregon state agencies, and others named on the app's attribution screen. Those sources keep their own licenses, and those licenses bind you too.

OpenStreetMap-derived data is licensed under the Open Database License 1.0. Using it carries obligations: attribute OpenStreetMap contributors, keep any derived database under the same license, and do not remove or obscure the attribution. The attribution screen inside the app and the credits on the web map are part of these terms.

Public-domain government data is not warranted by its publishers and is not warranted by Glassing, LLC.

6a. Share links

In the app or on the web map you can make a link to one waypoint, route, track or trip. A share link is the whole authorization: whoever holds it can open it, with no account, until it expires or you revoke it.

• What it shows is that record — its name, its notes, and every coordinate in it, never its photographs — on a page Glassing serves, or in the app of someone who has Glassing.
• You choose its life: a day, a week, thirty days, or until revoked. Revoking is immediate. A link that has expired or been revoked shows nothing and says nothing about whether it ever existed.
• You are the publisher. Where a link goes, who forwards it, and what a messaging service does with the preview is not something Glassing, LLC can control or take back.
• Deleting your account deletes every link you made.

6b. Glassing Data

Glassing Data's pages are free to read, with no account. Its JSON and GeoJSON data is licensed under the Creative Commons Attribution 4.0 International License (CC BY 4.0): you may copy, share and adapt it for any purpose, commercial or not, as long as you credit "Glassing Data" with a link to https://glassing.app/data and say if you changed it.

The license covers Glassing Data's own compilation: its statuses, rules, place matches and map shapes. What each row links to stays its publisher's. Forest Service and National Park Service orders and alerts, NIFC and WFIGS wildfire data, and USGS place names are U.S. Government works. Typical overnight lows are derived from PRISM climate normals (PRISM Climate Group, Oregon State University). Campground data comes from the USDA Forest Service, the National Park Service and Recreation.gov. Hunting seasons, tags and hunt boundaries come from the Oregon Department of Fish and Wildlife. Trailheads and their access rules come from the USDA Forest Service, the National Park Service and Recreation.gov, and trailheads in four national parks from OpenStreetMap contributors under the Open Database License. Credit them where you reuse their part.

Glassing Data was called Big Fluffy Puffy, and bigfluffypuffy.org now sends you to glassing.app/data. These terms cover it under either name.

7. Subscriptions and purchases

Glassing sells one subscription, through the App Store on iPhone or by card on glassing.app. Apple processes App Store payments and Stripe processes card payments. Prices, billing periods and any current offer are shown before you buy.

Subscriptions renew automatically. A subscription renews at the end of each period unless auto-renew is turned off at least 24 hours before the period ends. Your Apple Account is charged when the renewal is confirmed, within 24 hours of the end of the current period. Manage and cancel subscriptions in your Apple Account settings — Glassing, LLC cannot cancel one for you.

Bought on glassing.app, a subscription renews every year on the date it started, charged to the card you gave, until you cancel. Cancel any time from Account on glassing.app; it runs to the end of the year you paid for. The free month there takes a card up front and becomes a paid year on its last day unless you cancel before then. Refunds for a web purchase: write to hello@glassing.app.

A free trial runs one month, once per account. An unused portion of a free trial is forfeited when a subscription is bought during it, where the law requires that to be said.

Asking the map comes with a subscription, on glassing.app, up to 300 questions per account each month. Asking may be unavailable at times, including when the month's capacity for everyone runs out. Searching by name, address or coordinate stays free.

Offer codes are Apple's. A code Glassing, LLC gives you is redeemed through the App Store on Apple's terms, and what it grants is shown there before you redeem it.

Refunds for App Store purchases are Apple's. They are handled under the App Store Terms of Service, and Glassing, LLC cannot issue one. If a paid feature is withdrawn during a period you have paid for, write to hello@glassing.app.

8. What happens when a subscription ends

Ending a subscription never takes anything away from you.

• Everything you saved keeps working. Viewing, searching, exporting, downloaded maps, and navigating to waypoints you already have all continue, free, with no time limit.
• Making new things is what stops. Eight actions need a subscription: saving a waypoint, saving a new route, starting a recording, downloading a map, updating one, making a share link, and reading a trailhead's access rules or a campground's booking details. Asking the map stops too; searching does not. The trailheads and campgrounds stay on the map.
• A trip in progress finishes. A recording already running always saves, and full function continues for seven days after the app is first online and sees the subscription gone — so a lapse that happens on a mountaintop is not a lapse until you are home.
• Your data stays yours. Export waypoints, routes and tracks as GPX at any time, with or without a subscription and with or without an account. List and revoke your share links at any time, with or without a subscription.

9. The service, and changes to it

Glassing, LLC will try to keep sync working and offline maps available for download, but does not promise the service will be uninterrupted or error-free, and may change or withdraw parts of it. The app is designed so that this costs you as little as possible: your data lives on your phone, works offline, and exports to GPX.

Downloaded maps keep working whether or not the servers do.

10. Warranty disclaimer

To the fullest extent the law allows, Glassing is provided "as is" and "as available", without warranties of any kind, express or implied — including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. Glassing, LLC does not warrant that map data, elevation, slope, trails, land ownership, place names, street addresses, positions, fire-use restrictions, closures, wildfire data, hunting seasons, draw estimates, trailhead access rules, campground details, sun, shade and thermals, or answers to questions asked of the map are accurate, complete, or current.

Some jurisdictions do not allow the exclusion of implied warranties, so parts of this may not apply to you.

11. Limitation of liability

To the fullest extent the law allows, Glassing, LLC is not liable for indirect, incidental, special, consequential or punitive damages, or for lost data, lost profits, personal injury or death, arising out of your use of Glassing or your reliance on anything it displays. Total liability for any claim relating to Glassing is limited to the greater of the amount you paid Glassing, LLC in the twelve months before the claim, or fifty U.S. dollars.

Nothing here excludes liability that cannot lawfully be excluded, including liability for death or personal injury caused by negligence where that exclusion is prohibited.

12. Indemnity

You agree to indemnify Glassing, LLC against claims arising from your misuse of the app, your breach of these terms, content you store that you had no right to store, or content you published with a share link.

13. Apple

You and Glassing, LLC acknowledge that this agreement is between you and Glassing, LLC only, and not with Apple; Apple is not responsible for Glassing or its content. Glassing, LLC is solely responsible for Glassing and for any maintenance and support of it; Apple has no obligation to provide maintenance or support for Glassing. If Glassing fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to Glassing. Apple is not responsible for addressing any claim by you or a third party relating to Glassing, including product liability, regulatory non-compliance, or consumer protection claims, or for investigating or defending any third-party claim that Glassing infringes intellectual property rights. You represent that you are not located in a country subject to a U.S. Government embargo or designated a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of this agreement and may enforce it against you.

14. Governing law

These terms are governed by the laws of the State of Delaware, without regard to conflict-of-laws rules. Disputes will be brought in the state or federal courts located in Delaware, unless the law where you live gives you the right to bring them somewhere else — in which case it does.

15. Changes to these terms

These terms may be updated. If a change matters, the effective date above moves and the change is listed under "What changed". Using Glassing after that means accepting the new terms; if you do not, stop using the app and, if you like, delete your account.

16. Contact

Glassing, LLC — hello@glassing.app

What changed on November 2, 2026

• Private parcels. §1 says a business named after its owner still shows that name, and that the filter that removes people's names isn't perfect.
• Trailhead sources. §6b names the National Park Service, and OpenStreetMap for the trailheads of four national parks, among where trailheads come from.
• Campground sources. §6b names the National Park Service and Recreation.gov, with the Forest Service, among where campground data comes from.
• Campground details. §1 says a campground's season, fee and booking are a summary of the agency's pages, and theirs win; §10 names them among what is not warranted.
• Sunlight and thermals. §1 says they model a calm, clear day from the terrain, and real wind and weather override them; §10 names them among what is not warranted.
• What a subscription covers. §8 counts eight actions, adding reading a trailhead's access rules and a campground's booking details, as the app and the web map already do.

What changed on October 26, 2026

• Reporting an answer. §4 adds reporting an Ask the Map answer to what sends your content, and only on your instruction.

What changed on October 22, 2026

• Asking the map. §1 says answers can be wrong and are to be checked on the ground; §4 adds asking the map to what sends your content, and only on your instruction; §7 says it comes with a subscription, up to 300 questions a month; §8 says it stops when the subscription does; §10 names answers among what is not warranted.
• Trailhead access rules. §1 says the web map's trailhead rules are a summary of the Forest Service's and Recreation.gov's pages, and theirs win; §6b credits them; §10 names the rules among what is not warranted.

What changed on October 19, 2026

• Hunting seasons on Glassing Data get a paragraph in section 1: a copy of ODFW's regulations, never the regulations, with next year's points to draw and draw odds as Glassing's estimate. Section 6b names ODFW's part of the hunt data, and section 10 names hunting seasons and draw estimates among what is not warranted.

What changed on October 15, 2026

• Share links can be made in the app as well as on the web map (section 6a), and making one is among the actions that need a subscription (section 8).

What changed on October 10, 2026

• Importing a file on the web map points to the Privacy Policy for who receives the place names, which is now Anthropic.

What changed on October 9, 2026

• Closures on the map get a paragraph in section 1: a twice-daily copy of each land manager's order, never the order itself, and no closure drawn never means open.

What changed on October 8, 2026

• Glassing Data is covered. Big Fluffy Puffy is now Glassing Data at glassing.app/data, and these terms apply to it.
• Fire restrictions and wildfire data get their own paragraphs in section 1: a summary of the land manager's orders, never the order itself, and wildfire data as planning context rather than a safety tool. Section 10 names them among what is not warranted.
• Open data. Section 6b licenses Glassing Data's JSON and GeoJSON under CC BY 4.0, says how to credit it, and names the sources whose part stays theirs. Section 5 makes room for reusing it.

What changed on September 29, 2026

• Street addresses. Sections 1 and 10 now name the street addresses search finds among the public data Glassing shows and does not warrant.

What changed on September 28, 2026

• Route guidance. Section 1 now carries the notice Apple requires of an app that gives turn-by-turn directions.

What changed on September 5, 2026

• No private individual is named on a parcel card. §1's private-parcel paragraph is rewritten: a company owner is named, a person is not, and the parcel's own street address stands in a person's place.
• Nevada joins the eight states whose county assessors are credited.

What changed on September 4, 2026

• Private parcels are named in the safety section: a county tax roll's owner of record is a record, not a contact, and not permission to enter.
• Share links get a section of their own (§6a) and the exceptions in §4 that make them honest: a link publishes one record on your instruction, and an imported file's place names go to a model for icon suggestions.
• Acceptable use forbids using owner information to contact or harass anyone, and publishing where another person lives, hunts or camps.
• Attribution names county assessors among the sources.
• The trial runs one month, the length Apple's configuration actually carries, where the previous version said 30 days. Offer codes are named as Apple's.
• Account deletion is reachable from the web map as well as the app.
• Apple's section states that Glassing, LLC alone is responsible for maintenance and support, which Apple's minimum terms require.
• Indemnity covers content published with a share link.

What changed on September 3, 2026

• One subscription. Glassing sells a single yearly plan. The monthly plan and the lifetime one-time purchase were withdrawn before either was ever offered, and the sentences about them are gone.

What changed on August 23, 2026

• Land ownership is named in the safety section, with the plain statement that a boundary or an access flag in the data is not permission to enter.
• "Decision support, not a guarantee" is stated as the rule the layers are read by, rather than left implied.
• Subscriptions get real terms: auto-renew and its 24-hour windows, the trial, one trial per account, and refunds as Apple's.
• A new section says what expiry does — everything saved keeps working, four save-shaped actions stop, a trip in progress finishes, and GPX export never stops.
• The Open Database License is named, with the obligations it carries.
• The watch app and the web map's account are inside the agreement's scope.
• The voice follows DESIGN.md §2a: the subject is Glassing or Glassing, LLC. Sentences kept in legal register are marked in the source.
