DiveOne Planner — Cookie & Local Storage Policy

Short version
DiveOne Planner does not use advertising or cross-site tracking cookies. We use your browser's local storage to make the app work — remember your settings and saved plans, and keep you signed in. Usage analytics are optional and run only with your consent.
What we store on your device
| What | Type | Purpose | Category |
|---|---|---|---|
| Settings (units, language, conservatism) | localStorage | remember your preferences | Strictly necessary |
| Current plan & history | localStorage | offline planning; your local history | Strictly necessary |
Sign-in token (diveone-jwt) | localStorage | keep you securely signed in | Strictly necessary |
| Onboarding / disclaimer / consent flags | localStorage | not repeat onboarding; record your choices | Strictly necessary |
| Device identifier | localStorage | security / abuse prevention | Strictly necessary |
| Analytics state & events | localStorage / network | help us improve the Service | Optional — consent-based |
We do not set third-party advertising cookies and do not track you across other websites.
Your control
- Analytics: turn it on or off at any time in Settings.
- Everything else is needed for the app to function. You can clear it via your browser settings or the in-app "clear data" option — note this also removes locally saved plans.
Changes
For material changes we will post an updated version with a new effective date.
