Summary
Personal Document Keeper is built so that your documents stay on your phone. The app has no user accounts, no developer server, no advertising and no analytics or tracking tools. We do not collect, receive, sell or share your documents or personal information.
1. About this policy
This Privacy Policy explains how Personal Document Keeper (the "App"), published by Alamgir App Studio ("we", "us", "our"), handles information when you install and use the App on an Android device. By using the App you agree to this policy. If you do not agree, please do not use the App.
The App is a personal document organizer. It helps you store details and images of important documents (such as passports, IDs, licenses, insurance, certificates, contracts and membership cards), track their expiry dates, receive reminders, and keep encrypted backups.
2. Information we do and do not collect
We do not collect any personal information. Specifically:
- We do not require you to create an account, sign in, or provide your name or email address.
- We do not upload your documents, photos, scans, notes, PINs, tags or any other content to our servers. We do not operate servers for the App's content.
- We do not use advertising SDKs, analytics SDKs, crash-reporting SDKs or tracking cookies.
- We do not collect your location, contacts, call logs, SMS, microphone recordings or advertising ID.
- We do not sell, rent or trade any information about you.
Because the App does not send your data to us, we cannot see, recover, reset or delete the information stored in it.
3. Information you store in the app
Everything you enter or attach is saved locally on your device, in the App's private storage area, which other apps cannot normally access. This may include:
| Type of data | Examples |
|---|---|
| Document details | Title, document type, holder name, document number, country or issuing authority, issue and expiry dates, type-specific fields (for example policy number, provider, vehicle registration), notes |
| Attachments | Photos, scanned pages and PDF files that you add to a document |
| Organization data | Tags, custom categories, family profiles (names and relationships), reminder days, checklists and checklist items |
| Emergency information | Name, emergency contact phone number, blood group, allergies or medical notes, and other notes that you choose to enter |
| App settings | Whether PIN, biometric unlock, screen-capture protection and backup reminders are turned on; a salted hash of your PIN (never the PIN itself) |
| Subscription status | A small flag and timestamp that remember whether your Google Play subscription was recently verified, so the App can work briefly offline |
This data is provided and controlled by you. It stays on your device unless you choose to create a backup, share a document or export a PDF (see section 8).
Emergency information: if you turn on "Show on lock screen" in Emergency Access, the emergency details and any documents you marked for emergency access can be viewed from the App's lock screen without entering your PIN. Please add only information you are comfortable showing to someone who holds your unlocked-screen phone.
4. Permissions the app uses
| Permission / feature | Why it is used |
|---|---|
Internet (INTERNET) and network state (ACCESS_NETWORK_STATE) | Only to communicate with Google Play for subscription purchase and verification. The App does not use the internet to send your documents anywhere. |
Notifications (POST_NOTIFICATIONS) | To show expiry reminders and optional backup reminders. You can deny or turn this off at any time in system settings. |
Biometric (USE_BIOMETRIC) | To let you unlock the App with your fingerprint or face. Biometric data is handled entirely by Android; the App never receives or stores your fingerprint or face data - it only receives a "success" or "failure" result. |
| Camera (through the document scanner) | When you tap Scan, the Google ML Kit document scanner opens to capture pages. The App does not hold a general camera permission; scanning is handled by Google Play services and the resulting images are saved into the App's private storage. |
| File and photo pickers | When you choose files, Android's system picker is used. The App only receives the specific files you select. It does not request broad access to your storage or gallery. |
5. Third-party services
The App uses a small number of well-known components. We do not give them access to your documents.
- Google Play Billing - processes the yearly subscription and tells the App whether it is active. Google's handling of payment data is governed by the Google Privacy Policy and the Google Play Terms of Service. We never see or store your card or payment details.
- Google ML Kit Document Scanner - a Google Play services feature that detects page edges, crops and enhances scans. It runs on your device. Information about how Google Play services handles data is described in Google's privacy policy and the ML Kit terms.
- Android system components - AndroidX libraries (such as Room database, WorkManager for scheduling reminders, and BiometricPrompt) and the Glide image-loading library. These run inside the App on your device and do not transmit your data.
The App contains no advertising networks and no third-party analytics.
6. Subscription and payments
Using the App requires an active yearly subscription (currently priced at US$4.99 per year, or the equivalent local price shown in Google Play). Purchases, renewals, cancellations and refunds are managed entirely by Google Play. To cancel, open Google Play → Payments & subscriptions → Subscriptions → Personal Document Keeper, or use the "Manage subscription" button in the App.
We do not receive your name, email address or payment method. The App only learns whether a valid subscription exists for your Google account on that device.
7. Security
- Private storage: documents and attachments are kept in the App's private storage, not in your public gallery or Downloads folder.
- App lock: you can protect the App with a 4-6 digit PIN and optional biometric unlock. The PIN is stored only as a salted, slow hash (PBKDF2). After repeated wrong attempts the App imposes increasing waiting times.
- Automatic re-lock: the App asks for your PIN again after it has been in the background for a short time, and every time it is started fresh.
- Screen protection: by default the App blocks screenshots and hides its content in the recent-apps preview (you can change this in Settings).
- Encrypted files: backup files and secure-share files are encrypted with AES-256-GCM before they leave the App.
- Clipboard: when you copy a document number, it is marked as sensitive and the App asks Android to clear it after a short time.
No method of storage or electronic transmission is completely secure, and we cannot guarantee absolute security. You are responsible for keeping your device protected with a screen lock, keeping your operating system updated, and keeping any backup or shared files you create in a safe place. Information stored on a rooted or compromised device may be exposed.
8. Backup, restore, sharing and export
These features create files on your device. They are started only by you, and we do not receive them.
- Backup & restore: creates a single encrypted backup file (.lkb) containing your documents, attachments, profiles, checklists and settings. You decide where to save or send it (for example Google Drive, email, a USB drive). Once you move the file to another service, that service's own privacy policy applies. The backup does not use a password you must remember; it is encrypted with a key built into the App, so anyone who has both the file and the App could restore it. Please keep backup files private.
- Secure sharing: creates an encrypted file (.pdks) for one document, protected by a password you set and given an expiry time. The expiry is enforced by the App on the receiver's phone and cannot prevent someone who has the file and password from copying the information while it is still valid. Share only with people you trust.
- PDF export: creates a normal PDF of the documents you select. PDFs are not encrypted. Treat them as sensitive and delete them when no longer needed.
When you share or export a file, you choose the app or person that receives it. We are not responsible for how those recipients or services use the file.
Temporary copies of such files are kept in the App's cache and are cleaned up by the App, and they are removed when you uninstall the App.
9. Notifications and reminders
Reminders are scheduled and generated locally on your device by Android's WorkManager. The App checks your documents about once a day and shows a notification when a document reaches one of the reminder days you chose. No server or push-notification service is involved. A notification may display the document's title, so consider your lock-screen notification settings.
10. Retention and deletion
- Your data remains on your device until you delete it. You can delete a document, a profile (which also deletes that person's documents), a checklist or a tag at any time inside the App.
- Uninstalling the App permanently deletes all of its stored data from the device, including documents, attachments, settings and PIN data. Android auto-backup is disabled for the App, so its data is not silently copied to cloud backups.
- Backup, share and PDF files that you saved or sent outside the App are not deleted automatically - please remove them yourself.
- Because we do not hold your data on any server, we have no copies to delete on our side.
11. Children's privacy
The App is a general-purpose utility intended for adults and is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect information from children. Parents or guardians may use the Family Profiles feature to organize documents of family members, including minors; that information stays on the parent's device and is controlled by the parent.
12. Your rights
Depending on where you live (for example under the GDPR in the European Economic Area and UK, the CCPA/CPRA in California, or similar laws), you may have rights to access, correct, delete, restrict or export your personal data, and to object to or withdraw consent for processing. Since all your data is stored on your own device and we do not receive it, you can exercise these rights directly:
- Access / portability: view your data in the App, or export documents as PDF or create a backup file.
- Correction: edit any document or profile in the App.
- Deletion: delete items in the App or uninstall the App.
- Withdraw permissions: change notification or other permissions in Android settings.
We do not sell or share personal information for advertising, and we do not make automated decisions about you. If you have questions about your rights, contact us using the details below.
13. International users
The App is published from Bangladesh and may be downloaded worldwide. Because your documents are not transmitted to us, there is no cross-border transfer of your content by the App. Subscription processing by Google may involve transfers under Google's own policies.
14. Changes to this policy
We may update this policy from time to time, for example if the App's features change or if the law requires it. The "Last updated" date at the top shows the latest version. Significant changes will be reflected in the App's Google Play listing or in an App update. Continued use of the App after a change means you accept the updated policy.
