Last updated · 21 June 2026

DeckWatch (“the app”, “we”, “us”) is a work-planning tool for ship's deck officers. This policy explains what data the app handles and how. By using DeckWatch you agree to this policy.

Offline · Guest mode

Using DeckWatch without an account

DeckWatch can be used fully offline in guest mode. In guest mode, all your data — work plans, checklists, certificates, photos, notes and similar — is stored only on your device and is never transmitted to us or any third party.

Account · Cloud sync

Account & cloud sync (optional)

If you choose to create an account or sign in (via email/password or Google Sign-In):

Authentication and cloud storage are provided by Supabase, our backend provider, and protected by access controls so that only you — and any crew you share a vessel with — can access your data.

Attachments

Photos

Photos you attach to records are stored on your device and, if you are signed in, uploaded to your private cloud storage for sync. They are not used for any other purpose.

Dictation

Voice input

The app offers optional voice dictation for remarks. When you tap the microphone button, audio is processed by your device's built-in speech-recognition service (for example, Google) to convert speech to text. DeckWatch does not record or store raw audio.

On-device alerts

Notifications & reminders

With your permission, the app schedules local reminders on your device (for example, certificate expiry, defects and tasks). These are generated locally on your device; we do not send marketing or promotional notifications.
