01 The short version
We don't sell your data. We don't run ad trackers. We don't train external models on the content you save. Your library is local-first, and you can export or delete everything at any time.
The rest of this page is the detail behind that promise. If you'd rather just ask a person, write to developer@sentrylinelabs.com.
02 What we collect
We try to collect as little as we can get away with. In practice, that's:
- Account data — your email address and, if you set one, a display name. Needed to give you an account and to reach you.
- Your content — the links, notes, tags, and collections you create. Stored to provide the service and synced if you turn sync on.
- Billing data — handled by our payment processor. We see a plan, a status, and the last four digits of a card; we never store full card numbers.
- Operational logs — minimal, short-lived diagnostics (e.g. error traces, request timing) to keep the service healthy.
03 How we use it
We use the data above only to run the service: to authenticate you, store and sync your library, process payments, respond to support requests, and keep the system reliable and secure. That's the whole list.
We do not build advertising profiles, and we do not sell or rent personal data to anyone.
04 Legal basis
If you're in the EEA or UK, we process your data on these bases: contract (to provide the service you signed up for), legitimate interests (to keep the service secure and improve it), and consent where required, such as optional communications.
06 Retention
We keep your data for as long as your account is active. When you delete your account, we remove your content from our live systems promptly and from backups within 30 days. Operational logs are kept for a short window and then discarded. We retain billing records only as long as tax and accounting law requires.
07 Your rights
Depending on where you live, you may have the right to:
- Access a copy of the personal data we hold about you.
- Correct data that's wrong or out of date.
- Export your content in a portable format — available any time from the app.
- Delete your account and associated data.
- Object to or restrict certain processing.
To exercise any of these, write to us. We'll verify your request and respond within 30 days.
08 Security
We encrypt data in transit and at rest, scope access tightly, and design for local-first storage so less of your data ever has to leave your device. No system is perfectly secure, but we treat your data the way we'd want ours treated, and we'll notify affected users promptly in the unlikely event of a breach.
10 Children
The service isn't directed at children under 16, and we don't knowingly collect their data. If you believe a child has given us personal data, contact us and we'll delete it.
11 Changes
We'll update this policy as the service evolves. Material changes update the effective date above, and account holders are notified by email for significant ones. The current version always lives at this URL.
