Privacy Policy
How we handle personal data when you use Ja-ti. This page is a practical summary for transparency; it is not legal advice. Have it reviewed for your jurisdiction (for example UK GDPR) before you rely on it commercially.

Who we are
Ja-ti operates the follower-tracking service at this site. For privacy questions or requests, contact support@ja-ti.com.
At a glance
- We process account data (email, session), product data (handles you track), and billing signals from our payment partner.
- We use PostHog for optional product analytics when configured: page views, product events, error reporting, and (for signed-in users) a stable account identifier plus properties such as email and plan to keep person profiles accurate.
- We use cookies and local storage for login, security, and (when analytics are on) anonymous or identified analytics IDs.
- You may have rights to access, correct, delete, or export data depending on where you live.
Data we process
- Account: email address, session and security data, optional verification state, and internal account identifiers.
- Product usage: X usernames and IDs you ask us to track, follower metrics we derive, update intervals, and notification preferences.
- Billing: handled by Autumn (and its processors). We receive billing status from Autumn to gate features; we do not store full card numbers in Ja-ti.
Analytics and product improvement
When our PostHog integration is enabled (project configuration in our hosting environment), we use PostHog to understand how the product is used and to diagnose client-side errors. That may include automatic page views, UI interactions (where autocapture is on), custom product events, and exception reporting.
Visitors receive an anonymous analytics identifier stored in first-party cookies and/or local storage. When you sign in, we associate activity with your stable account ID (a UUID in our database, not your email as the primary key in PostHog) and may send person properties such as your email address, subscription plan, email verification state, and an internal staff flag where applicable, so PostHog can show a consistent profile for support and product analysis. When you sign out, we clear the analytics link on that browser so future events are not attributed to your account unless you sign in again.
PostHog processes data as our processor; their own privacy information is published at posthog.com/privacy. Where PostHog is not configured, this category of processing does not run.
Processors and infrastructure
We use service providers to run the product, including hosting (for example Cloudflare), email delivery, databases, the X/Twitter data API, Autumn for subscriptions, and—when enabled—PostHog for analytics. They process data only as needed to provide the service.
Retention
We keep data while your account is active and for a limited period afterwards for security, legal, and operational needs, then delete or anonymise it where appropriate.
Your rights
Depending on your location, you may have rights to access, correct, delete, or export personal data, and to object to or restrict certain processing. Contact us at the address above. You may also complain to your local data protection authority.
