Privacy Policy

Last updated September 1, 2026

Salt is a personal watersport logbook. This page explains, in plain language, exactly what data the app collects, why it's collected, and where it's stored. If anything here is unclear, contact us using the details at the bottom of the page.

In short: your data is stored in the EU, on Supabase (our database and authentication sub-processor). We don't sell your data, and we don't share it with advertisers. It's used only to run the app for you — to remember your sessions and to match upcoming conditions against them.

Data we collect

The table below lists everything Salt stores about you, grouped by what it's used for.

Category What's stored Why
Account Email address Sign-in, account recovery, and so friends can find you when they know your email
Profile First and last name, profile photo, home spot (name & coordinates), selected sports, matching preferences (wind/wave tolerance, search radius), profile visibility setting Personalizing the app, showing your profile to people you allow to see it, and tuning forecast matching to your sports and preferences
Sessions Sport, spot name and GPS coordinates, start/end time, stoke rating, notes, an optional photo, and a snapshot of conditions at the time (wind speed/gusts/direction, wave/swell height, period and direction, current speed/direction, tide phase, air/water temperature, weather, precipitation, cloud cover, UV index), plus your feedback on forecast accuracy The core of the app — this history is what Salt learns from to tell you when future conditions are worth going out for
Gear Sport, category, name and size of gear you add Letting you attach the gear you used to a session, and remember what you own
Social Who you follow and who follows you (via a QR code you choose to share) Letting you see friends' sessions if you follow each other — one-way, and only after you've explicitly shared or scanned a follow code

Device permissions

Salt asks for a few permissions on your device, each used only for the feature named:

Where your data is stored

Salt uses Supabase as its database, authentication and file storage sub-processor. Your data — account, profile, sessions, gear and follow relationships — is stored on Supabase infrastructure hosted in the European Union. We don't run our own servers for this data; Supabase is the only third party that holds it on our behalf.

To show weather and marine forecasts, the app also sends the latitude/longitude and time you're asking about to Open-Meteo, a weather data provider. That request only carries the coordinates and timestamp needed to fetch a forecast — it does not include your name, email, or any other account information.

What we don't do

Data retention & deletion

Your data is kept for as long as your account exists, so the app can keep learning from your session history. You can delete individual sessions or gear at any time from within the app. To delete your account and all associated data entirely, contact us at the address below — we'll remove it from Supabase within 30 days.

Your rights

If you're in the EU/EEA, UK, or a jurisdiction with similar protections, you have the right to access, correct, export, or delete your personal data, and to object to or restrict how it's processed. To exercise any of these rights, contact us — we'll respond within 30 days.

Children's privacy

Salt is not directed at children under 16, and we don't knowingly collect data from them.

Changes to this policy

If this policy changes in a meaningful way, we'll update the date at the top of this page. Continued use of the app after a change means you accept the updated policy.
