Your location

Legal basis

We process your data because it is necessary to provide the service you use (performance of a contract), and for security and preventing abuse (legitimate interest). For location and notifications your device asks for your permission first; you can withdraw it at any time in your phone's or browser's settings.

Who is data shared with?

We do not sell your data and do not share it with anyone else, unless the law requires us to.

How long do we keep data?

Security

All connections are encrypted (https). Passwords and keys are stored only as a hash, never readable. The data is stored encrypted on Cloudflare's servers. Login attempts are limited to prevent guessing.

Cookies and local storage

Tick only uses what is necessary: a cookie to keep you logged in, a cookie for your language choice, and local storage in your browser so the app works offline and remembers your display settings. There are no tracking or advertising cookies.

Your rights

You have the right to access your data, have it corrected or deleted, receive a copy (in Tick itself: Settings › Data › Backup), and to object to or restrict processing. Send an email to dio@ticktodo.nl; you will get an answer within one month.

Deleting your account: email dio@ticktodo.nl from your account's email address and ask for your account to be deleted. We delete it within 30 days and let you know when it is done.

If you disagree with how we handle your data, you can file a complaint with the Dutch Data Protection Authority, the Autoriteit Persoonsgegevens.

Children

Tick is not intended for children under 16.
