SeaCal is developed and published by Gavin Kerr, Ireland. For the purposes of the EU General Data Protection Regulation (GDPR) and the Irish Data Protection Acts 1988–2018, Gavin Kerr is the data controller for any personal data processed in connection with this application.
For users in the United Kingdom, this policy also applies under the UK General Data Protection Regulation (UK GDPR) as retained and amended by the Data Protection Act 2018. The UK GDPR mirrors the EU GDPR in structure and rights; all obligations and protections described in this policy apply equally to UK residents.

All of the following is stored exclusively using your device's local storage. It is never transmitted to our servers, third parties, or any cloud service:
When you use the built-in backup feature, an export file is created on your device and shared only to destinations you explicitly select (e-mail, iCloud, Google Drive, etc.). We never receive or have access to a copy of your backup.
We use Google Firebase Analytics to understand how the app is used in aggregate so we can improve it. The data collected is anonymous and non-identifiable; it includes:
Firebase Analytics does not receive any maritime data described in Section 2. Google processes this data under its own privacy policy (firebase.google.com/support/privacy).
SeaCal is free to use and is supported by advertising served by Google AdMob. To serve relevant ads, Google may use:
AdMob does not receive any of the maritime data you enter into SeaCal. Google's advertising privacy policy is at policies.google.com/privacy.
How to opt out of personalised ads:
Once every seven days the app makes a brief outbound HTTPS request to fetch a small configuration file hosted on GitHub Pages. This request contains no personal data — it carries no cookies, user identifiers, or content from your records. It is used only to confirm the app is up to date and whether certain features (such as ads) are enabled.
| Data type | Leaves your device? | Shared with | Purpose |
|---|---|---|---|
| Maritime records, certificates, days, profile | Never | Nobody | App functionality |
| Anonymous usage events (screen views, sessions) | Yes | Google (Firebase) | App improvement |
| Ad identifier (IDFA / GAID) | Yes (with consent on iOS) | Google (AdMob) | Ad personalisation |
| Device model, OS version, country | Yes | Google (Firebase / AdMob) | Analytics & ads |
| Config fetch (HTTPS GET, no body) | Yes | GitHub (read-only) | App version check |
Anonymous analytics and advertising data processed by Google may be transferred to and stored on servers outside the European Economic Area (EEA). Google complies with EU data transfer requirements through Standard Contractual Clauses (SCCs) approved by the European Commission.
For users in the United Kingdom, data transferred outside the UK is governed separately under UK GDPR. Google uses either UK International Data Transfer Agreements (IDTAs) or the UK Addendum to the EU Standard Contractual Clauses, both approved by the UK Information Commissioner's Office (ICO), to safeguard transfers of UK residents' data to servers outside the UK.
As a resident of the EU or UK you have the following rights. To exercise any of them, contact us at seacal.app@gmail.com. We will respond within 30 days.
SeaCal is designed for maritime professionals aged 16 and over. We do not knowingly collect personal data from anyone under 16. If you believe a child has provided personal data through the app, please contact us at seacal.app@gmail.com and we will take steps to delete it promptly.
The following third-party services may process data as described above:
No other third parties receive data from this application.
We may update this policy as the app evolves — for example if paid features or in-app purchases are introduced. Material changes will be reflected in an updated "Last updated" date at the top of this page. Continued use of the app after changes are posted constitutes your acceptance of the revised policy.
