1. Scope
This policy applies to the Nook Todo apps for iOS and Android and the official website at nooktodo.com.
2. App data
Tasks, categories, display names, completion history, settings and attachments are stored on the user’s device. Data shared within a household group is encrypted and synchronised between participating devices. We do not operate a central database that stores task content or names.
3. Accounts and identifiers
Nook Todo does not require an email address, phone number or third-party login. Cryptographic keys generated on the device identify the user and device.
4. Invitation links
The secret required to join a group is stored in the URL fragment after #. Standard HTTPS requests do not send that fragment to the web server. The invitation page does not display or store the group name, task content or secret.
5. Notification relay
When remote notifications become available, we may process a device token, an irreversible hash of the group ID and the event time to deliver a notification. Task content and names will not be processed in plain text. This policy will be updated before that feature is released.
6. Website
This website does not use advertising cookies, analytics SDKs or fingerprinting. Cloudflare may temporarily process technical information such as IP address, User-Agent and access time to provide hosting and security.
7. Sale and disclosure
We do not sell user data. Except where required by law, we do not disclose task content or names to third parties.
8. Deleting data
You can remove locally stored data by leaving the app group and deleting app data from the device. Shared data already synchronised to another participant’s device may remain on that device.
9. Children
Nook Todo is not directed at children and does not intentionally collect children’s personal information.
10. Changes
We may update this policy as the product or applicable law changes. Material changes will be announced on this page or in the app.
11. Contact
A contact channel will be published here as part of the app release preparation.
