Account and authentication
An account is required to use SundaMind. Processed data: email address and a hashed password. Authentication is provided by Supabase (1 Letterman Drive, San Francisco, CA 94129, USA), with hosting in the EU (Frankfurt, Germany) on the basis of Standard Contractual Clauses pursuant to Art. 46 GDPR.
Legal basis: Art. 6(1)(b) GDPR (contract performance).
Usage data and health data (Art. 9 GDPR)
SundaMind processes self-entered data on mood, sleep, energy, connection, body, focus, calm and meaning (mood logs), journal entries, rituals and completed experiments. These entries may constitute health data within the meaning of Art. 9 GDPR.
Processing is based solely on your explicit consent pursuant to Art. 9(2)(a) GDPR. You may withdraw your consent at any time with effect for the future by deleting your account or removing the entries.
Purpose: provision of self-tracking and reflection features, personalized hints within your own account.
AI-assisted processing
For the Companion (journaling prompts), pattern analysis and experiment recommendations features, your inputs are transmitted per request to the API of Anthropic PBC (548 Market St, San Francisco, CA 94104, USA). Transfers to the United States are based on Standard Contractual Clauses pursuant to Art. 46 GDPR and additional safeguards (TLS in transit, no training use).
No automated individual decision-making, including profiling, with legal effect within the meaning of Art. 22 GDPR takes place. Outputs are non-binding suggestions and do not replace diagnosis or therapy.
A local crisis-keyword detection runs before each AI call. If a crisis hint is detected, the app surfaces support resources and the AI call is not executed.
Hosting and technical connection data
Database and authentication are hosted on Supabase (region EU Frankfurt). The app may be delivered via content delivery networks that process technically necessary connection data (e.g. IP address, browser information, timestamps) to operate the service and defend against attacks.
Legal basis: Art. 6(1)(f) GDPR (legitimate interest in secure operation).
Cookies and local storage
SundaMind uses session tokens for authentication and your device's localStorage for language, theme and gamification state. This data does not leave your device.
Retention and deletion
Your data is retained for as long as your account exists. You can delete individual entries at any time.
To delete your entire account, use the app settings. Deletion takes effect immediately and covers the associated data — journal entries, check-ins and analyses — not just your access. You confirm by entering your email address.
One exception: feedback you submitted under an explicit promise of anonymity. For those entries the personal reference is removed while the entry itself remains, and an anonymised entry can no longer be traced back to you.
If you no longer have access to your account, you can request deletion by emailing werner-productions-media@protonmail.com. After we receive the request, all personal data is removed within 30 days unless statutory retention obligations apply.
Rights of data subjects
You have the right to access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing (Art. 21).
Please send requests by email to werner-productions-media@protonmail.com.
