4. Legal Basis (GDPR)

Under the GDPR, we rely on the following legal bases to process your personal data:

Legitimate interest— for basic analytics and security, where this does not override your rights.
Legal obligation— where we are required by law to retain or disclose data.

5. Cookies

We use cookies and similar technologies to make our site work, remember your preferences, and understand how the site is used. Essential cookies are required for the site to function. Analytics and marketing cookies are only set with your consent. You can manage or withdraw your consent at any time through your browser settings.

6. Third-Party Services

We use carefully selected third-party providers to deliver our services. These providers process personal data on our behalf under data processing agreements that comply with the GDPR:

Mixpanel— product analytics, used to understand how visitors interact with our website and app.
Supabase— database infrastructure, used to store newsletter and waiting list signups.

Some of these providers may transfer data outside the European Economic Area. Where this happens, we ensure appropriate safeguards are in place, such as the EU Standard Contractual Clauses.

7. Data Retention

We keep personal data only for as long as necessary for the purposes set out in this policy. Newsletter data is kept until you unsubscribe. Analytics data is kept in aggregated form for a limited period and then deleted or anonymized.

8. Your Rights Under the GDPR

As a data subject in the EU/EEA, you have the following rights:

Access— request a copy of the personal data we hold about you.
Rectification— ask us to correct inaccurate or incomplete data.

Lodge a complaint— with your local data protection authority. In Sweden this is the Integritetsskyddsmyndigheten (IMY).

To exercise any of these rights, please contact us at hay@hayhayapp.se. We will respond within 30 days.

9. Data Security

We take reasonable technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet is 100% secure.
