Privacy, by default.

We built this studio to make software that respects the people using it. That starts with your data. Here's exactly what we collect, why, and the lines we won't cross.

Effective · June 6, 2026 Version · 2.1 rev #7e9d10

01 The short version

Sentry line

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.

05 Sharing & processors

We share data only with a short list of vetted processors who help us operate, and only as much as they need:

  • Cloud hosting — to store and serve data.
  • Payment processing — to handle subscriptions securely.
  • Email delivery — to send transactional messages like receipts and password resets.

Each is bound by a data-processing agreement. We may also disclose data if required by law — and where we're allowed to, we'll tell you first.

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.

09 Cookies

Our website uses only the cookies needed to make it work — for example, to keep you signed in. We don't use advertising or cross-site tracking cookies, and there's no third-party analytics following you around.

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.
