Privacy Policy

Last updated October 14, 2026

Datums is built to keep your data yours. This policy explains what's collected, by whom, and why. It's provided by Homaro ("we", "us").

Without sync

Everything you log stays in your browser, on your device, encrypted. Nothing is sent to us or anyone else. There are no accounts, no analytics, no ads, and no trackers.

With sync

• Your email address is used to sign you in (with a one-time code) and to link your subscription to your account.
• Your entries and settings are encrypted on your device before they're uploaded, and stored by our sync provider, Dexie Cloud (dexie.org). Neither we nor Dexie Cloud can read them: only your devices, unlocked with your passphrase, can.
• What the sync server can see: your email address, an id for each entry, roughly how many entries you have and how large they are, and when your devices sync. It can't see your entries' times, tags, values, colors, or saved filters.

Payments

Payments are handled by Paddle.com, our reseller and Merchant of Record, under its own privacy policy. We never see your card details. Paddle tells us the status of your subscription, your customer id, email address, and country, which we use only to turn sync on or off for your account. Paddle's checkout script is loaded only when you open checkout.

Keeping and deleting data

Synced data stays on the sync server while you have an account, including after a subscription ends, so you can pick up where you left off. To have your account and synced data deleted, contact us at support@datums.online. Data on your devices is under your control: clear it from Settings in the app.

Your rights

Depending on where you live, you may have rights to access, correct, delete, or export your personal data, and to complain to a data protection authority. Contact us to use them. We don't sell or share your data.

Changes and contact

We'll update this page if anything changes, and mention significant changes in the app. Questions: support@datums.online.
