DaytailPrivacy policy
You can use Daytail's planning features without an account. This policy covers local planning, optional sync and feedback, advertisements in the free version, and the optional Daytail Plus purchase.
Your planner
Semesters, courses, assignments, exams, grades, timetable entries, notes, preferences and reminder schedules are stored on your device. Optional sync sends planner records and selected preferences to Supabase, along with your account identifier and email address. Google and Supabase process authentication information if you choose Google sign-in. Daytail uses this information to provide its features and synchronize your devices. We do not sell your planner data or provide it to advertisers.
Advertisements
The free version may show labelled Google native advertisements on Today and Tasks. Where required, consent choices are presented before ads are requested. Available privacy choices can be revisited from Settings. Google Mobile Ads may collect and share IP address (which can indicate approximate location), device and account identifiers, interactions such as launches and taps, and diagnostic information for advertising, analytics and fraud prevention. See Google's privacy policy and its SDK data disclosure. Your Android advertising ID can be reset or deleted through device settings. Verified Plus owners receive no ads; Daytail does not start ad requests while checking initial purchase ownership. Daytail has no separate behavioral analytics service.
Daytail asks for an age range, without collecting a birth date. This choice is stored only on your device and is excluded from planner sync, exports and backup. Ads stay off until you choose a range. Users under 18 and those who prefer not to say receive ads with restricted data processing and general-audience content limits. Adults can make applicable advertising consent choices through Google's consent form. You can change your age range and revisit available consent choices in Settings.
Daytail Plus
Google Play processes payment for the optional one-time purchase. Daytail does not receive payment card details. Our Supabase verification function sends the purchase token to Google Play to check the product, purchase status and acknowledgement, then returns a signed receipt. The token and receipt are saved in private device storage and excluded from planner backups and sync. Previously verified access remains usable offline. Verification uses a hashed network address to prevent abuse; old rate-limit records are removed after two days when new requests are processed. Daytail does not store raw purchase tokens in that database. Restore purchase checks ownership through your Google Play account. Deleting a Daytail sync account does not cancel your Play purchase; payment and refund controls remain with Google Play.
Feedback
Your message and optional reply address wait in a private device outbox until delivery. Supabase passes the message to Brevo for email delivery to daytail.help@outlook.com. An opaque message ID, a one-way network-address hash and delivery status help prevent abuse and duplicate delivery; feedback text is not stored in that rate-limit table. Support emails remain in the mailbox while needed to handle the request. You can review or remove queued messages in Settings.
Notifications and backups
Reminder calculations happen on your device. Android delivers notifications. Exported backups are saved to the location you choose. Android backup may copy the planner database to your backup account according to device settings. Account sessions and Plus purchase receipts are excluded from planner exports and configured Android backups.
Security and deletion
Local data is stored in app-private storage. Optional cloud data is protected by Supabase row-level policies restricting records to the signed-in user. Internet requests use HTTPS. Administrative keys, payment credentials and private receipt-signing keys are not included in the app.
Local information remains until you delete it, clear app storage, or uninstall and remove any operating-system backup. Synced information remains until you delete records or your account. Account deletion removes your cloud account and its associated Daytail records. You can export data, disable notifications or sync, sign out, manage available ad privacy choices, or permanently delete your account from Settings. An external account-deletion page is also available.
Children and changes
Daytail is a general education productivity tool, not directed specifically to children under 13. A parent or guardian should supervise account use where local law requires it. Material changes will be reflected here with an updated date. Contact daytail.help@outlook.com with privacy questions.
