How to delete your account and data

The quickest way is in the app (Android and iPhone):

  1. Open Kerzu and go to Settings.
  2. Choose “Delete account”.
  3. Confirm. Your account and data are removed right away and the phone is signed out.

No app at hand? Write from your account's e-mail address to the contact address above asking to “delete my account”; we will delete it within 30 days.

We delete: the account and profile (e-mail, name), all your devices and their access, sessions, screen images and offer card crops, offers, trips, location, telemetry, reports, settings and summaries. For Apple accounts we also revoke the Sign in with Apple token.

Only an entry in the administrator's event log stays, saying that an account was deleted (no personal data). Database backups expire after 14 days.

Frequently asked questions

What does the app do?

While you drive it reads the offer card in Uber Driver and Bolt Driver and shows zł/h, zł/km and a colour (green, yellow, red). In the evening it summarises your day and week. Kerzu never taps anything for you.

What data does it collect?

Only while you record: screen images of the Uber Driver and Bolt Driver apps, offer and trip data, GPS position and technical data. Plus the e-mail and name of your Google or Apple account and a random installation ID. We use no advertising ID and no Android ID. Details and retention periods: the privacy policy.

How do I stop recording or the accessibility service?

Stop recording with STOP in the app; on iPhone also with the screen recording button in Control Center. Turn the accessibility service (optional, Android only) off in system Settings → Accessibility → Kerzu.

How do I disconnect a device?

In the app: Settings → “Disconnect device”. This phone's token stops working; your account and data stay. To delete the data too, use “Delete account”.

Is Kerzu affiliated with Uber or Bolt?

No. Kerzu is an independent app by Freshcore and is not affiliated with Uber Technologies or Bolt Technology.

I cannot sign in. What now?

Check that you use the same Google or Apple account as before and that the phone is online. If that does not help, write to us with your phone model and the app version.
