Singletrack Privacy Policy

Effective October 8, 2026

Singletrack is a mountain bike app, a product of tukool.dev ("we", "us"). This policy explains what the app collects, why, who sees it, and your choices. Questions: tukool.dev [at] gmail [dot] com.

What we collect

• Account. The email address and sign-in details you use to create an account, and a display name.
• Rides. The routes you record: GPS positions, times, speeds, distances and the trails you ride.
• Live location, only when you share it. If you choose to share with friends while you ride, your current position is shared with those friends.
• Friends. Who you are friends with in the app, and who you share your location with.
• Safety alerts. If a stop or help alert is raised during a ride: its time, your position, and who you chose to ride with.
• Emergency contacts. The name and mobile number of each person you add to be texted in an emergency, and whether they have opted out.
• Device. A push notification token for your phone, so alerts can reach it.

How we use it

• To record, save and show your rides, and to show friends where you are when you share.
• To alert the riding partners you chose, and to text your emergency contacts, when you need help.
• To run and secure the service and fix problems.

We do not sell your data, and we do not use it for advertising.

Text messages to emergency contacts

See also how emergency contact texts work. When you add an emergency contact, you confirm that the person knows about it and agrees to get texts. We send them one message saying you added them. If you then need help during a ride, they get a text with your name, your last location and who you are riding with, and later a text when you are OK or when a riding partner is on the way. These texts are sent for safety only, never for marketing, and they are rare.

• A contact can reply STOP at any time to stop all texts, and HELP for help.
• Message and data rates may apply. Message frequency varies and is tied to alerts, so it is usually none.
• Phone numbers collected for these texts are used only for them. We do not share them for marketing or with anyone other than the service providers below.

Who else handles your data

• Supabase hosts our database, accounts and server functions.
• Twilio delivers the text messages.
• Google Firebase Cloud Messaging delivers push notifications to phones.
• Map and weather sources such as OpenStreetMap and the U.S. National Weather Service receive the map area or position needed to show tiles and conditions.

We may also disclose information if the law requires it, or to protect someone's safety.

How long we keep it

Your rides and account stay until you delete them or ask us to. Live location is removed when your ride ends or you stop sharing. Alert records are kept for a limited time to run the service and are then deleted. You can remove an emergency contact in Settings at any time, which removes their number from our records.

Your choices

• Turn off partner alerts, change who you ride with, or stop sharing your location, in the app.
• Remove an emergency contact in Settings.
• To access, correct or delete your data or your account, email tukool.dev [at] gmail [dot] com.

Safety, not a guarantee

Singletrack's alerts are a helpful extra, not a replacement for calling emergency services. Alerts depend on phone signal, battery, settings and other things outside our control, and may be delayed or not delivered. In an emergency, call 911.

Children

Singletrack is not for children under 13, and we do not knowingly collect their information.

Changes

If we change this policy we will update the date above and, for significant changes, tell you in the app.
