Your data stays on your device. Zenvar has no accounts, no analytics trackers, and never sells data. Zenvar is not directed at children under 13.
Zenvar is operated by Finn Quintus, based in Portugal. Contact: finnaquintus@icloud.com.
Your supplement stack, goals, dose history, daily check-ins (energy, sleep, focus), and streaks are stored locally on your phone. We cannot access them. Deleting the app deletes this data.
When you use an AI feature (Stack Report, smart search, or label scanning), the app sends only what that feature needs to our server, which forwards it to Anthropic (our AI provider) to generate a response:
Requests include a random device identifier used solely for rate limiting. It is not linked to your name, email, or any other identity — we never collect those. AI requests are not stored on our servers and are processed transiently. Rate-limit counters are stored for 48 hours and then automatically deleted. Anthropic processes requests under its privacy policy and does not train models on this data.
If you connect Apple Health, Zenvar queries HealthKit for sleep, step count, and heart-rate variability (HRV) data. This data stays entirely on your device — it is used only for on-device trend and correlation analysis and is never sent to any server. You can disconnect Apple Health at any time from within the app, or revoke access via Settings > Health > Data Access & Devices.
Dose reminders are scheduled locally on your device. No notification data is sent anywhere.
To delete all your data, delete the app. All local data is removed immediately. We do not retain any personal data on our servers.
If you are in the European Economic Area or United Kingdom, you have rights under the GDPR. The legal basis for processing the anonymous device identifier is legitimate interest (rate limiting). All other personal data is stored only on your device. To exercise your right to erasure, delete the app. For any data rights requests, contact us at the email below.
