This page explains how users of "DaySprinter" (the "Service"), provided by MeSight Inc. (the "Company"), can delete their Account and data, and which data is deleted or retained.

1. App and provider

  • App: DaySprinter
  • Provider: MeSight Inc.

2. Deleting your Account in the app

You can delete your Account from within the app, on both iOS and Android.

  1. Open the Settings tab.
  2. Tap Account.
  3. Tap Delete account.
  4. Type the word shown on the screen to confirm, and then tap Delete account.

This action cannot be undone.

3. If you cannot use the app

If you cannot use the app, you can request the deletion of your Account by email.

  • Send an email requesting the deletion of your Account to support@me-sight.com.
  • To verify your identity, please send the email from the email address registered to your Account.

The data deleted is as set out in "4. Data that is deleted".

4. Data that is deleted

When your Account is deleted, the data stored on the Company's servers is deleted immediately. The data deleted includes account information, measurement data, purchase status, and device tokens. The Company does not retain deleted data for any period (so-called logical deletion).

For users who use Sign in with Apple, the link with Apple is also revoked when the Account is deleted in the app.

5. Data that is retained and for how long

  • The database used by the Company includes automatic backups for the purpose of recovery from failures. The retention period for these backups is at most 24 hours, so deleted data is erased from the backups within approximately 24 hours at the latest. The Company does not restore or use personal data from those backups.
  • The Company retains personal information only for the period necessary to achieve the purposes of use and, after that period, deletes it except where retention is required by law (see section 9 of the Privacy Policy).

6. If you use the app without signing in

Registering an Account is optional. Without a registered Account, measurement data stays on your device and is not stored on the Company's servers, so there is no Account to delete.

To delete the data on your device, open the Settings tab, tap Delete all data in the Data section, type the word shown on the screen to confirm, and then tap Delete all. All tasks, measurement records, and segments will be deleted. This can't be undone.

7. Paid Plans

Deleting your Account and cancelling a Paid Plan are separate procedures. For cancellation, see Article 10 of the Terms of Service.
