This policy explains what we collect, why, and the choices you have. We designed ZiWei Compass to collect as little as possible: there is no account system, and your birth data is processed in your browser and stored on your device.
The data controller is the operator of ZiWei Compass. You can contact us at hello@ziweicompass.com for any privacy request.
We do not sell your personal data. We share it only with: our payment provider (to process purchases), our hosting provider (to run the site securely), and authorities where legally required.
Birth data stays on your device until you delete it. Purchase records (email, license, order) are kept as long as needed to provide the service and to meet tax/accounting obligations, then deleted or anonymised.
Depending on where you live (e.g. GDPR in the EU/UK, CCPA in California), you may have the right to access, correct, delete, or port your data, to object to or restrict processing, and to lodge a complaint with your local data protection authority. Contact us to exercise these rights.
Our providers may process data in countries other than yours. Where required, we rely on appropriate safeguards such as standard contractual clauses.
ZiWei Compass is not intended for children. It is aimed at adults and is not directed to anyone under 18.
We use browser local storage to keep your saved charts and license status on your device. We do not use advertising trackers.
We may update this policy; the effective date above will change. Continued use after an update means you accept the revised policy.
