Privacy Policy

This page explains what CLSTR collects, why, and the choices you have. We try to collect as little as possible.

CLSTR is operated as an independent project based in the EU. For privacy or legal questions, contact info@clstr.news.

What we collect

Account data. When you sign in we store your email address, display name, and (if provided by Google) profile picture URL. We use this to authenticate you and to send service emails.

Subscription data. If you upgrade to a paid plan, billing is handled by Stripe. We store a Stripe customer/subscription identifier and the plan status. We do not see or store card details.

Product data. Items you create on the service (followed topics, briefing and monitor preferences) are stored against your account.

Logs. Our infrastructure processes standard request data such as IP address and user agent for security, abuse prevention, and rate limiting. These logs are short-lived.

Cookies

CLSTR only sets cookies that are strictly necessary to run the service. We do not use advertising or cross-site tracking cookies.

• Session cookie: keeps you signed in after authentication. Expires after 7 days of inactivity.
• Sign-in state cookie: set briefly during Google sign-in to protect against CSRF. Discarded right after sign-in completes.

For analytics we use Simple Analytics, which is cookieless and does not profile visitors.

Third parties that receive your data

• Cloudflare: hosting and web services.
• Google: sign-in, only when you choose to sign in with Google.
• Stripe: subscription payments, only for paying users.
• Simple Analytics: privacy-friendly, cookieless usage statistics.

Other services we use to build the product (such as news APIs and AI providers) do not receive any of your personal data.

Email

If you sign in by magic link, we send a one-time link to your email. If you enable briefings or Pro monitors, we send those emails on the schedule and triggers you configure (with links to unsubscribe without signing in). You can change this anytime from Automations in your account.

Retention

We keep account and product data for as long as your account exists. If you delete your account, associated personal data is removed; minimal billing records may be retained where required by law.

Your rights

Depending on your jurisdiction (including the EU/UK under GDPR), you may have the right to access, correct, export, or delete your personal data, and to object to certain processing. To request account deletion or to exercise any of these rights, email support@clstr.news and we will action your request.

Children

CLSTR is not directed at children under 16 and we do not knowingly collect their data.

Changes

We may update this policy as the service evolves. Material changes will be reflected in the "Last updated" date above.
