Privacy Policy

A Line a Day — Android / iOS

Last updated: September 13, 2026

Summary

A Line a Day collects nothing. There is no account, no sign-in, no server of ours, no analytics, no advertising, and the app requests no permissions. Every sentence you write stays on the device you wrote it on, and we have no way to read it.

1. What this policy covers

This policy covers the A Line a Day mobile app for Android and iOS (the “app”). It does not cover the App Store or Google Play themselves — those are separate companies with their own policies.

2. What we do not collect

We do not collect, transmit, or have any technical means to read:

• the sentences you write (your cards);
• your name, email address, phone number, or any account identifier;
• your location, contacts, photos, calendar, or health data;
• device identifiers, advertising identifiers, or your IP address;
• usage statistics, session recordings, or crash reports.

There is no analytics SDK, no advertising SDK, no crash-reporting SDK, and no third-party code that sends anything off your device. The app contains no networking code at all: it never opens a connection.

3. Where your cards live

Your cards, the card background you chose, and your language choice are stored in the app’s private storage on your own device (on Android, the app’s private data directory; on iOS, the app’s container). Nothing is uploaded anywhere.

Two important consequences:

• If you uninstall the app, or lose the device, the cards are gone. There is no copy on our side — we cannot recover them, and we cannot read them.
• If someone else can unlock your phone, they can read your cards by opening the app. The app has no lock of its own.

4. What happens when you share a card

When you tap “Make a card”, the app draws the card as a PNG image, writes it into the system’s temporary folder, and hands it to the operating system’s share sheet. You choose the destination (Messages, WeChat, AirDrop, a cloud drive…). From that point, the app or service you selected handles the file under its own privacy policy. We never see the image, and we are not told that you shared it.

5. Backups (export and import)

Export writes one file containing your cards (the text and the date of each) into the temporary folder and hands it to the system share sheet, so you can save it wherever you like. The contents are wrapped so that other software opening the file sees unreadable text — but please note it is not encryption: the key is inside the app. Do not treat a backup file as if it protected sensitive text.

Import opens the system file picker and reads only the single file you choose; nothing else on your device is touched.

The exported file lives wherever you put it. If you store it in a cloud drive, that provider’s policy applies, not ours.

6. Permissions

The app asks Android for no permissions at all (its manifest contains no permission declarations), and it asks iOS for none either: no notifications, no photos, no contacts, no tracking. The limited system features it uses — the share sheet and the file picker — are provided by the operating system and require no permission.

7. Purchases and payments

The app is sold as a paid download through the App Store or Google Play. Your payment is handled entirely by Apple or Google; we never receive your name, email address, card details, or billing address. The stores give us sales figures that contain nothing identifying an individual buyer.

If a future version adds an in-app purchase, the store will process that too, and this policy will be updated before it ships.

8. Children

Because the app collects no data at all, it also collects no data from children. There is nothing to delete and nothing is shared with anyone.

9. Your rights and choices

Data-protection laws (GDPR, CCPA and similar) give you rights to access, correct, delete, and move your data. Your cards exist only on your device, so you exercise all of those directly:

• Access, correct, delete — in the app; every card can be edited or deleted.
• Move it elsewhere — use Export (section 5).
• Erase everything — delete your cards in the app, or uninstall it.

We have nothing to hand over and nothing to erase on our side, because we never received anything.

10. Changes to this policy

If this policy changes, this page is updated and the “last updated” date above changes.

Terms of Use

A Line a Day — Android / iOS

Last updated: September 13, 2026

Summary

The app is licensed, not sold. It is provided “as is”, without warranty, and you are responsible for your own backups. That is the whole agreement, in one sentence.

1. License

A Line a Day is licensed to you, not sold. The license is personal, non-exclusive, and non-transferable, and it lets you install and use the app on devices you own or control, for personal, non-commercial purposes, under the rules of the App Store or Google Play you bought it from.

You may not: copy, resell, rent, sublicense, or redistribute the app; reverse-engineer, decompile, or disassemble it (except where the law expressly permits); or remove or alter any copyright or other proprietary notices.

2. No warranty

The app is provided “as is” and “as available”, without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the app will be error-free, that defects will be corrected, or that your data will never be lost or corrupted.

3. Your data, your responsibility

Your cards are stored only on your own device. You are responsible for keeping backups of anything you cannot afford to lose. Use the Export feature regularly if your entries matter to you. We have no copy of your data and cannot recover it for you.

4. Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, revenue, or goodwill, arising out of or related to your use of, or inability to use, the app. Our total liability for any claim relating to the app will not exceed the amount you paid for it.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages; in those places, some of the above may not apply to you.

5. Acceptable use

You agree to use the app only for lawful purposes and in compliance with all applicable laws. You must not use the app to store or share content that is illegal, infringing, or harmful to others.

6. Changes to the app and to these terms

We may update the app and these terms from time to time. The “last updated” date above will change when we do. Continued use of the app after a change means you accept the updated terms.

7. Termination

You can stop using the app at any time by uninstalling it. We may terminate this license if you materially breach these terms.

8. Contact
