Sirena LogbookPrivacy Policy
Sirena Logbook for iPhone. Effective 10 October 2026.
1. Who we are
Sirena Logbook is published by Anton Dimitrov, a sole trader established in Varna, Bulgaria ("we", "us"). For any privacy question or request, write to [email protected]. The EU General Data Protection Regulation (GDPR) applies.
2. The short version
Sirena Logbook has no account and no server. Your documents, scans, document details and contracts are stored only on your iPhone. We never receive them, we cannot read them, and we cannot recover them for you.
3. What the app keeps on your iPhone
| Data | Why | Where |
|---|---|---|
| Scanned pages of your documents | So you can see and show your documents | Your iPhone, in files iOS keeps encrypted and unreadable while the phone is locked |
| Document details: type, name, number, issuer, issue and expiry dates, your notes | To list your documents and remind you before they expire | Your iPhone |
| Contracts: vessel, IMO number, flag, rank, dates, day split | To count your sea service and make the PDF | Your iPhone |
| Settings, such as the Face ID lock | To remember your choices | Your iPhone |
Text on your documents is read by Apple's on-device text recognition. The images are not sent to us or to anyone else for this.
Like other app data, this data is part of your iPhone backup if you back up your iPhone to iCloud or to a computer, so a new iPhone restored from that backup keeps it. Those backups belong to you and are handled by Apple or your computer, not by us.
4. Permissions
Camera: only to scan documents when you tap Scan. Face ID: to unlock the app; iOS checks your face and only tells the app yes or no. Notifications: to remind you about expiry dates; reminders are scheduled on your iPhone.
5. Purchases
Logbook Pro is sold by Apple through the App Store. Apple is the merchant and handles payment, taxes and refunds under its own privacy policy. The app only asks Apple whether you have an active subscription. We do not receive your payment details.
6. What we do not do
No analytics, no advertising, no tracking across apps or websites, no data brokers, no sale or sharing of personal data. The app makes no network requests of its own; the only connections are to Apple for purchases and to the web pages you open from Settings.
7. Deleting your data
Delete a document or a contract inside the app, and it is removed from your iPhone together with its scans. Deleting the app deletes everything it stored on the iPhone. There is no account to close.
8. Your rights
Because we hold no personal data about you, there is usually nothing for us to give, correct or erase. You still have every right under the GDPR and may write to [email protected], and you may complain to the Bulgarian Commission for Personal Data Protection (cpdp.bg) or to the authority where you live.
9. Children
Sirena Logbook is meant for working seafarers and is not directed at children.
10. Changes
If a future version starts to handle data differently, for example an optional encrypted backup, we will update this policy before that version is released and show the new date above.
