DriveSafe

Last updated: August 4, 2026

DriveSafe records your drives from your phone’s sensors and scores how smoothly you drove. This page describes exactly what the app collects, where it goes, and how to get rid of it. It is written from the app’s source code, not from a template.

What DriveSafe reads from your phone

• Location (GPS). While a trip is recording, DriveSafe reads your position about once a second to draw your route, measure distance, and work out where you were driving rather than walking or stopped. Recording continues with the screen off, which is why the app asks for “Always” location access; iOS shows the blue location indicator the whole time. Location is only read between the moment you tap Start and the moment the trip ends.
• Accelerometer and gyroscope. While a trip is recording, DriveSafe reads your phone’s motion sensors 20 times a second. This is the raw material for the smoothness score — sudden inputs read as high jerk.
• Photo library. Only if you choose to add a profile photo, and only the one image you pick. The app never browses your library on its own.

DriveSafe does not read your contacts, calendar, microphone, camera, health data, messages, or browsing activity. It contains no advertising and no analytics or tracking SDKs of any kind.

What is stored on your phone

Everything below stays on your device and is never uploaded:

• Your trips, including full routes, while you are using DriveSafe without an account.
• Your profile photo.
• Your reaction-check history and settings.

Deleting the app removes all of it.

What is stored on our server

If you sign in with Apple, your trips are backed up to our database (hosted by Supabase) so they survive a lost or replaced phone. Each trip row holds:

• start and end time, duration, distance, and the time zone the drive happened in
• your smoothness score and the score-over-time trace behind it
• the notable events found in the drive (hard braking, cornering, phone handling) and where in the drive they happened
• your route, as a list of coordinates each tagged with a smoothness value

Your account itself holds only what is needed to sign you in and address you by name: the account identifier Apple gives us, the email address Apple shares (if you chose Apple’s “Hide My Email”, we only ever see the relay address), and the first and last name you enter.

Every trip row is tied to your account and protected by row-level security, so one account cannot read another’s data. Your profile photo is not uploaded.

Signing in is optional. The whole app works without an account, and trips recorded without one stay on the phone. The first time you sign in, DriveSafe asks whether trips already on the phone belong to you: choose “Add” and they are uploaded to your account, choose “Don’t add” and they are deleted from the phone.

What we never do

• We do not sell your data.
• We do not share it with advertisers, data brokers, or any third party, and we do not use it to track you across other apps or websites.
• We do not use your driving data to set anyone’s insurance rates, and we do not give it to insurers or employers.

The only third party involved is Supabase, which hosts the database and authentication on our behalf and does not use your data for its own purposes.

Deleting your data

• In the app: Settings → Account → Delete account. This permanently deletes your account, every trip synced to it, and the copies on your phone. It cannot be undone.
• Deleting a single trip: swipe or long-press a trip in Recent trips, or tap Discard on a debrief.
• Signing out clears this account’s trips from the phone but keeps them on the server, so they come back when you sign in again.
• Uninstalling removes everything on the phone. If you had an account, use Delete account first to remove the server copy too.

Children

DriveSafe is meant for licensed drivers and drivers with a learner’s permit. It is not directed at children under 13 and we do not knowingly collect their data.

Changes

If this policy changes in a way that affects what we collect, the updated version will be published here before the change ships in an app update.
