Privacy Policy
Last updated: October 1, 2026
Your data belongs to you. Pick your app below — each one has the same promise: everything stays on your device unless you explicitly opt into the cloud.
Portside
Nautical logbook · Offline-first with optional Cloud Sync
What's stored on your device
- Vessel names, call signs, IMO numbers
- Port names, arrival and departure dates
- Rank held and session sign-on records
- Coordinates you enter
- Offline map regions you download
All of this stays on your phone unless you turn on Cloud Sync.
Cloud Sync (optional)
If you create an account, your vessel records are transmitted to and stored on Supabase (supabase.com) so they can be restored on another device. Supabase acts as our data processor and stores data on our behalf; it does not use your data for any purpose other than storage and retrieval.
Data stored on Supabase:
- Your email address (for authentication only)
- A randomly generated User ID (UUID) used to link records to your account
- Vessel records you mark for sync — vessel name, call sign, IMO, port calls, dates, ranks, coordinates, notes
Data NOT stored on Supabase:
- Your live location (used only in-memory to center the map; never transmitted)
- Offline map tiles (downloaded directly from OpenFreeMap and stored on your device)
All communication with Supabase is encrypted in transit using HTTPS/TLS.
You can delete your Supabase-stored data at any time from within the app: Settings → Account → Delete Account. This permanently removes your user record and all vessel records from Supabase.
You can use Portside entirely offline without ever creating an account.
Transactional email
Portside sends confirmation and password-reset emails via Resend (resend.com), a transactional email delivery service. When you sign up or request a password reset, your email address is transmitted to Resend so the email can be delivered.
Resend retains email delivery logs for up to 45 days, after which they are automatically deleted. Resend does not use your email for marketing or any purpose other than delivering the emails you requested.
Portside does not send newsletters, promotional emails, or any marketing communication.
In-app purchases (Mariner Pro)
Portside offers an optional one-time in-app purchase - Mariner Pro, a routing upgrade priced at $14.99 USD. Purchases are processed entirely by Google Play Billing.
We do not receive or store your payment method, card details, or billing address. Google Play handles the transaction and shares only the purchase confirmation with us so the feature can be unlocked on your account.
No additional personal data is collected for Mariner Pro beyond your existing Google Play account. For refunds and payment disputes, Google Play standard processes apply; see the Mariner Pro section on the Portside page.
Location
Portside asks for location permission only to center the map on your position and to fill in coordinates when you tap "Use current location." Your location is never stored, transmitted, or shared.
Offline maps
When you download an offline region, tiles are fetched from OpenFreeMap's public server and stored on your device. No personal information is sent during this process.
Data deletion
You can delete your account and all synced data at any time from within the app: Settings → Account → Delete Account. This permanently removes your user record and all vessel records from our servers.
Local data stored on your device can be cleared separately from Settings → Storage & Data.
If you cannot access the app, you may also request deletion by emailing [email protected] from the address associated with your account. Deletion requests sent by email are processed within 7 days.

Data deletion
Uninstalling LSA & FFE permanently removes all locally stored data. You can also clear everything from within the app's Settings using Reset to default register.
Because LSA & FFE does not collect any data, no deletion request or email is necessary.
Coordinates Converter
DMS ↔ Decimal · Fully offline, no data collection
Coordinates Converter does not collect any data
Coordinates Converter runs entirely on your device. It has no accounts, no cloud, and no internet permission — the app literally cannot connect to any network.
Specifically, Coordinates Converter does not:
- Require an account or sign-in
- Request internet permission (it cannot go online even if you wanted it to)
- Include analytics, crash reporting, or advertising SDKs
- Read your contacts, photos, or any other device data

Location permission
Coordinates Converter requests location permission only to fill the coordinate fields when you tap Use my current location. The value is used immediately, in-memory, and is never stored, transmitted, or shared.
Location permission is optional. You can use the entire app without granting it — manual entry works identically.
What's stored on your device
- Your current input and format preference (DMS or Decimal)
- Theme preference (follows your system by default)
Nothing else. There is no history, no saved list, no cached location.
Data deletion
Uninstalling Coordinates Converter removes all local data. There is no server-side copy to delete.
Because Coordinates Converter does not collect any data, no deletion request or email is necessary.
