Data sharing and transfers
Analytics data is processed by Google, which may store and process information in the EU and the United States. We use Cloudflare Zaraz to route analytics through a first-party context, which helps limit third-party access to your data. Where transfers outside the EU occur, they are covered by appropriate safeguards such as the EU-US Data Privacy Framework or Standard Contractual Clauses.
Data retention
- Analytics data in GA4 is retained for a maximum of 14 months, after which it is automatically deleted.
- Cookie durations are listed in the table above.
- Personal information you provide (e.g. by email) is retained only as long as necessary to handle your request or comply with legal obligations.
Your rights
You have the right to:
- Request access to your personal data.
- Request correction or deletion of your data.
- Withdraw consent at any time (for example, disabling analytics cookies).
- Restrict or object to processing in certain circumstances.
Requests regarding your rights can be sent to info@hydrovolta.com.
