Terms of Service

Effective November 9, 2026

These terms apply to your use of the Trailquill app, provided by an individual developer (“we”). By using Trailquill you agree to them. Please also read the Privacy Policy.

Using the app

Trailquill helps you keep a hiking journal, plan trips and pack lists, and view your trailheads on a map. Your journal is stored on your iPhone. The app has no cloud sync or backup of its own, so your data does not move to a new device and is lost if you delete the app or the account. You are responsible for your device and any device backups.

Accounts

To use Trailquill you create an account with Sign in with Apple, Google or an email address and password. In the current version this account is created and kept only on your iPhone; we hold no copy and cannot recover it or reset a password. You are responsible for the information you enter and for keeping your device secure. You can sign out or permanently delete an account at any time in Me › Account. See Account deletion.

Scout, the AI assistant

Scout’s answers are generated by an AI model (DeepSeek, through our server) and can be wrong, incomplete or out of date. Scout may save planned trips and pack lists to your journal; you can undo its latest action and edit or delete anything it saves. Scout is available only after you agree to the AI consent screen, needs an internet connection and has a daily message limit. We may change, limit or discontinue Scout at any time.

Outdoor safety

Hiking and backcountry travel carry real risks, including injury and death. Everything in Trailquill is for information and record-keeping only. That includes Scout’s trip plans, itineraries, pack lists and safety notes, and the app’s distances, elevations, time estimates, difficulty ratings, maps, satellite imagery and coordinates. It is not a substitute for official trail information, a navigation device, a map and compass, training, or your own judgment.

• Scout has no live weather, trail-closure, permit, fire or avalanche data and cannot tell whether a route is open, legal or safe.
• Before you go, check official sources such as land managers, park websites, rangers and forecasts, and get any permits you need.
• Carry proper navigation and safety equipment, tell someone your plan, and turn back when conditions change.
• The emergency safety card is stored only on your iPhone. The app does not contact anyone or call for help on your behalf. In an emergency, call your local emergency number.

You decide whether, where and how to hike, and you accept the risks of doing so.

Your content

You own the hikes, notes, photos and other content you add. Because it stays on your iPhone, we do not receive it, except for what you send to Scout, which we and DeepSeek process only to generate answers as described in the Privacy Policy. You are responsible for having the rights to the content you add.

Acceptable use

Don’t use Trailquill or Scout to break the law or infringe others’ rights; don’t send unlawful, abusive or harmful content to Scout; don’t try to bypass message limits, overload, probe or reverse engineer our server; and don’t use Scout to build a competing service.

Disclaimers

Trailquill is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the app or Scout will be uninterrupted, error-free or accurate.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special or consequential damages, or for personal injury, property damage, or loss of data arising from your use of the app, Scout’s suggestions or any outdoor activity. Our total liability for any claim relating to the app is limited to the amount you paid for it, if any. Some jurisdictions do not allow these limits, so they may not fully apply to you.

Termination

You may stop using Trailquill at any time by deleting your account and the app. We may suspend or end access to Scout if you breach these terms or if we discontinue the service. Sections on outdoor safety, disclaimers and limitation of liability continue to apply.

Apple

These terms are between you and us, not Apple. Apple’s standard Licensed Application End User License Agreement also applies to your use of the app downloaded from the App Store.

Changes

We may update these terms as the app changes. The effective date above shows the latest version; continuing to use the app after a change means you accept it.
