Change log: on October 31, 2026 we added an Android (Google Play) section. The text below applies to the iOS version and is unchanged. The Android version follows the Android section.

This policy describes version 2.1.0. In 2.0.x, iCloud Sync covers only tasks and repeating tasks (not list names or completion history), and tasks named like a When'd I item are linked automatically.

• We collect nothing. The developer does not collect, store, or receive your tasks, memos, or usage data. No analytics, advertising, or tracking tools.
• On your device: tasks, memos, lists, repeating-task rules, settings, and completion history (History keeps every entry). Deleted items, including lists and completion entries removed by unchecking, are kept in an on-device trash (latest 2,000 per kind). An on-device sync log contains only counts and error codes, and leaves the device only if you export it yourself.
• iCloud Drive backup (free): one backup file in your own iCloud Drive so you can restore after reinstalling. Stored by Apple under Apple's privacy policy.
• iCloud Sync (Pro, only if you turn it on): syncs on-device lists (list names), tasks, repeating tasks, and completion history (History) through your private CloudKit database. Completion history also includes Notion tasks you finished (task name and date); memos and Notion tasks themselves are not synced. Only you can access it by default; the developer cannot see it. Task names, task notes, list names, and the task names in completion history are encrypted on device before upload; dates, completion status, repeat type, and the IDs that identify lists and tasks are not. Deleted items stay in iCloud with a "deleted" mark (including their content) so other devices can apply the deletion. To remove everything, delete this app's data in your iCloud storage settings. The app also reads one setting from a CloudKit public database to be able to pause sync remotely; no user data is sent.
• Notion (Pro, only if you connect): reads and writes tasks and memos in the Notion databases you allow, via Notion's official API (Notion's privacy policy applies: https://www.notion.com/privacy). The sign-in token is stored only in this device's keychain. Sign-in passes through our relay server on Cloudflare Workers, which only relays the token exchange and stores nothing (Cloudflare's privacy policy applies).
• When'd I (Pro, only if you turn it on): if our app When'd I is on the same device, finishing a task you linked to When'd I records the date and time there, on device only, through a shared App Group. You turn the link on yourself (the When'd I icon on the task row, or the Link check when adding); tasks with the same name are linked together, and a task is never linked just because When'd I has an item with that name. For an existing item only the item ID, date, and time are written; for a new name you linked, the task name is also passed so When'd I can create the item.
• Purchases: handled by the App Store. We do not receive payment information.
• Deleting data: deleting the app removes its on-device data; the Notion token may remain in the iOS keychain until the app is reinstalled and first opened, and you can revoke it in Notion. iCloud data and the iCloud Drive backup remain until you delete them in your iCloud storage settings.

This section applies to the Android version distributed on Google Play. The iOS version follows the iOS policy above.

• We collect nothing. The developer does not collect, store, or receive your tasks, memos, or usage data. No ads, no analytics, no tracking tools, no advertising ID.
• On your device: tasks, memos, lists, repeating-task rules, settings, and completion history are saved in the app's private storage. The app is excluded from Android cloud backup; Drive sync state, the Notion sign-in, and the active display state are not carried over in device-to-device transfers. By default the Show notification displays the current task title on the lock screen; turn on "Hide task titles on the lock screen" in Settings to hide it.
• Google Drive sync (Pro, only if you turn it on): uploads one file (whatdoido-sync.json) containing the default list's tasks, repeating tasks, and "deleted" markers (with their content) to this app's private hidden space (appDataFolder) in your own Google Drive, so your Android devices signed in with the same Google account stay in sync. The app requests only the drive.appdata permission and cannot read your other Drive files or contacts. To tell which Google account is connected and to show it on screen, the app receives that account's email address from Google and stores it on this device only; it is not sent to the developer. Memos, completion history, and other lists are not synced. The file is not separately encrypted by the app; transfer uses HTTPS and Google stores it under Google's privacy policy (https://policies.google.com/privacy). The developer cannot see it.
• Notion (Pro, only if you connect): reads and writes tasks and memos in the Notion databases you allow through Notion's official API (Notion's privacy policy applies: https://www.notion.com/privacy). The sign-in token is encrypted with an Android Keystore key and stored in non-backup app storage. Sign-in passes through our relay server on Cloudflare Workers, which only relays the token exchange and stores nothing (Cloudflare's privacy policy applies: https://www.cloudflare.com/privacypolicy/). Changes made offline wait in an on-device queue until the network returns.
• When'd I (Pro, only if you turn it on): if our app When'd I is on the same device, finishing a task you linked records the date there, on the device only, through an Android ContentProvider. What Do I Do checks that the other app is When'd I (package name and Play signing key) before sending anything, and When'd I checks the caller the same way. For an existing item only the item ID, date, and record ID are sent; for a new name you linked, the task name is also sent. When'd I installed on the device lets What Do I Do read When'd I's item names to show them.
• Purchases: handled by Google Play Billing. We do not receive payment information. The app stores whether you own Pro and checks your purchases with Google Play when you open the app.
• Third parties: we do not provide or sell your information to third parties. Google (Drive, Play), Notion, and Cloudflare are used only for features you choose to use.
• Permissions: notifications (the Show notification and the optional morning notification), Android 16 promoted notifications, internet (Drive sync, Notion, and the Notion sign-in relay only), and receiving the boot-complete signal to reschedule notifications and alarms. No location, contacts, photos, microphone, or camera.
• Deleting data: uninstalling the app removes its on-device data and the encrypted Notion token. Drive sync data can remain in your Google Drive's app data until you delete it in Google Drive's app settings. Notion data is managed in Notion. The developer holds no user data to delete.
• Children: this app is intended for users 13 and older.
• Changes: if this policy changes, we will post it on this page with the effective date.
