Lab4 (“we”, “us”) builds focused software utilities. This policy explains what personal data we collect, why, and your rights over it. We keep data collection minimal and never sell it.
Lab4 is operated from the European Union. For any privacy question, or to exercise the rights below, contact hi@lab4.app. We are the data controller for the data described here.
We use PostHog to understand how the site is used — page views, referrer, approximate location, device/browser, and UTM campaign parameters. This helps us measure interest and traffic sources. Legal basis: our legitimate interest in operating and improving the site.
If you sign up on the Android SBS page, we collect the details you submit:
Legal basis: your consent, given when you tick the box and submit the form. We send at most an occasional update about Android SBS. You can withdraw consent and unsubscribe at any time via the link in any email, or by emailing us.
We share data only with service providers who process it on our behalf:
Waitlist data is kept until the Android SBS demand test concludes or you unsubscribe — whichever is first — after which it is deleted. Analytics data is retained per PostHog's standard retention.
Under the GDPR you can request access to, correction of, or deletion of your data, object to or restrict its processing, and request portability. To exercise any of these, email hi@lab4.app. You also have the right to lodge a complaint with your local data protection authority.
We may update this policy. Material changes will be reflected by the date above.
