Hydrolock is a digital‑wellbeing app that encourages hydration by requiring you to take a picture of water before unlocking distracting apps. The pause snaps you out of autopilot so you can stay hydrated and decide whether opening that app is really worth it.
Hydrolock offers two subscription options:
We built Hydrolock for anyone tired of doom‑scrolling yet frustrated by screen‑time limits with an "Ignore" button. By combining habit-building for hydration with app blocking, we created a double win for your health and digital wellbeing.
Hydrolock is currently available on iOS globally. We plan Android support and wider regions soon.
Android support is in active development.
Yes. Photos are never saved by us. All analytics events are anonymised.
On first network connection, Hydrolock registers an anonymous install — no email or password required.
Hydrolock needs camera access to verify your water photo, and notification access to alert you when you open a locked app to start the unlock process.
You can delete your account from Settings → Danger Zone → Delete Account.
Hydrolock falls back to a "soft lock" mode and reminds you that a camera is required. You can still browse past stats, but launches won't be intercepted until permissions are restored.
When you tap a blocked app, Hydrolock launches first, prompts you to take a picture of water, verifies your hydration, and then gives you a session‑length picker (15 min, 30 min, 1 h, 6 h, rest of day).
You can allow the target app for 15 min, 30 min, 1 hour, 6 hours, or the rest of the day. Once the timer ends, the intercept re‑engages automatically.
Yes, Hydrolock includes configurable skips for edge cases when you need immediate access to an app. These can be adjusted in the Settings menu.
Behaviour events (e.g. "unlock_attempt", "session_started") are sent to PostHog for anonymised product analytics. No personal identifiers or photos are transmitted.
Hydrolock focuses on encouraging hydration at key moments rather than comprehensive tracking. We measure unlock attempts but don't track actual water consumption volumes.
Only to validate unlock attempts. Your photos are never used for advertising, AI training, or sold to third parties.
No. Photos are processed by us and then deleted immediately.
Photos are never saved. Server‑side logs (push tokens, subscription receipts) are retained while your subscription is active, then purged within 30 days of account deletion.
Each event is stripped of personal identifiers, batched, and transmitted over HTTPS. PostHog stores only anonymous install IDs, event names, and basic device metadata (OS version, locale).
