SameDue Privacy Policy
Last updated: October 24, 2026
1. Who we are
SameDue is a mobile app for iOS and Android that helps you plan recurring tasks for your home, car, hobbies and the clients you work for. It is developed and operated by 11App ("we", "us", "our"). We are the controller of the personal data described in this policy.
In short: we keep your data to run the app for you. We never sell it, show no ads, and do not track you across other apps or websites.
Questions or requests: support@11app.dev.
2. Information we collect
We collect only what you give the app and what it needs to work. Everything you enter is stored in your own account and is visible only to you.
| Category | What it includes | Where it comes from |
|---|---|---|
| Account | Email address, display name, profile photo, sign-in method, account ID, when you accepted the Terms | You, or Google / Apple when you sign in with them |
| Spaces and tasks | Space names, notes, icons, colours and photos; task titles, descriptions, schedules, durations and time zone; each date's status, notes, and before / after photos | You |
| Clients (optional) | Name, contact person, email, phone, address, country, VAT ID, notes and custom fields of the people you work for | You |
| Business and invoices (optional) | Your business name, address, registration number, VAT ID, IBAN, email, phone, currency, tax settings and signature; issued invoices and work reports | You |
| Devices and notifications | Push notification token, platform (iOS / Android), device time zone, notification preferences | Your device |
| Subscription | Plan, status, store (Apple / Google), renewal and expiry dates. We never receive your card or payment details | Apple App Store or Google Play, through RevenueCat |
| Diagnostics | Crash reports: device model, OS version, app version, the state of the app when it crashed, and your account ID | Your device, through Firebase Crashlytics |
| App integrity | A token proving that requests come from a genuine copy of the app | Apple App Attest / Google Play Integrity, through Firebase App Check |
Information about other people. When you add a client, or put their details on an invoice, you give us their personal data. Make sure you are allowed to do so. We process it only to provide the app to you, and you are responsible for it towards those people.
Photos and camera. The app asks for camera or photo library access only when you choose to add a photo. Only the photos you pick are uploaded. Each is resized on your device and stamped with the time it was added.
What we don't collect. No precise location, contacts, advertising identifiers or browsing history. The app contains no advertising or analytics SDKs. Your appearance preference (light / dark) stays on your device.
3. How we use your information
| Purpose | Legal basis (GDPR) |
|---|---|
| Create and secure your account; sign you in with email, Google or Apple | Performance of our contract with you |
| Store and sync your spaces, tasks, dates, photos, clients and invoices across your devices | Performance of contract |
| Send the daily reminder digest (one push at 9:00 in your time zone, if notifications are on) | Performance of contract; you can turn it off at any time |
| Provide Premium: check your subscription, restore purchases | Performance of contract |
| Fix crashes and keep the service reliable | Our legitimate interest in a working app |
| Protect the service from abuse and fake clients (App Check) | Our legitimate interest in security |
| Answer your support requests | Performance of contract / legitimate interest |
| Comply with legal obligations (e.g. tax records for purchases kept by the stores) | Legal obligation |
We do not use your data for advertising, profiling or automated decisions with legal effects, and we do not sell or rent it.
4. Service providers and sharing
We share data only with providers that run parts of the service for us, under contracts that bind them to protect it:
| Provider | What it does | Data involved |
|---|---|---|
| Google Firebase (Google LLC / Google Ireland Ltd): Authentication, Cloud Firestore, Cloud Storage, Cloud Functions, Cloud Messaging, Crashlytics, App Check | Accounts, database, file storage, reminders, push delivery, crash reports, app integrity | All data described in section 2 |
| Google Sign-In | Signing in with your Google account | Name, email, profile photo |
| Sign in with Apple (Apple Inc.) | Signing in with your Apple ID | Name and email (or Apple's private relay address) |
| RevenueCat, Inc. | Managing subscriptions | Account ID, purchase and subscription status |
| Apple App Store / Google Play | Processing payments, refunds and push delivery (APNs) | Handled under Apple's and Google's own privacy policies |
We may also disclose information if the law requires it, to protect the rights and safety of our users or others, or as part of a sale or transfer of the app, in which case this policy continues to apply to your data.
5. Where your data is stored
Your data is stored on Google Cloud infrastructure; our server functions run in the European Union (Belgium). Some providers (Google, Apple, RevenueCat) may process data in the United States or other countries. Where data leaves the European Economic Area, the transfer is covered by the European Commission's Standard Contractual Clauses or the EU–US Data Privacy Framework.
6. How long we keep it
- Your account and content: as long as your account exists.
- Push tokens: until you sign out on that device, or the token stops being valid.
- Crash reports: up to 90 days.
- Issued invoices: they stay in your account until you delete the account. Keeping copies for your own tax records is your responsibility.
- Purchase records: kept by Apple, Google and RevenueCat as their own policies and the law require.
7. Deleting your account
You can delete your account at any time in the app: Profile → Delete account. This permanently deletes your profile, spaces, tasks, dates, photos, clients, invoices, business details, devices, settings and subscription record, revokes Sign in with Apple, and then deletes your sign-in account. It cannot be undone. Backups held by our providers are overwritten within their normal cycles.
Deleting your account does not cancel a subscription. Cancel it in your App Store or Google Play account settings.
If you no longer have the app, write to support@11app.dev from the email address on the account, or use our account deletion page.
8. Your rights
Depending on where you live (for example under the GDPR, UK GDPR or California law), you have the right to:
- access the personal data we hold about you and get a copy of it;
- correct inaccurate data (most of it you can edit in the app yourself);
- delete your data (see section 7);
- restrict or object to processing based on our legitimate interests;
- receive your data in a portable format;
- withdraw consent where we rely on it, e.g. notifications or camera access in your device settings;
- lodge a complaint with your local data protection authority.
To use any of these rights, write to support@11app.dev. We answer within 30 days and may need to confirm that the account is yours. We do not sell or share personal information for cross-context behavioural advertising.
9. Security
Data travels encrypted (TLS) and is encrypted at rest by Google Cloud. Database and storage rules allow each account to read and write only its own data, and App Check blocks requests that don't come from the genuine app. No system is perfectly secure; keep your password safe and tell us at once if you suspect misuse of your account.
10. Children
SameDue is not directed at children under 13 (or the higher minimum age for using online services without parental consent in your country, such as 16 in some EU countries). We do not knowingly collect data from them. If you believe a child has given us personal data, contact us and we will delete it.
11. Changes to this policy
We may update this policy as the app changes. We will change the "Last updated" date above and, for significant changes, tell you in the app or by email before they take effect.
