Local by default
Your dashboard, settings, trends, reminders, alarms, and most daily rhythm calculations are stored and processed locally on the device.
Privacy policy
Privacy that stays calm, clear, and local-first.
BioClock is built to make rhythm more visible without turning your wellbeing data into a product. Core features work on-device, optional integrations stay optional, and the app is framed as informational support rather than diagnosis or medical judgement.
At a glance
What BioClock is trying to protect.
BioClock is a wellbeing-oriented BioTime and circadian app. It estimates rhythm-related patterns such as BioTime, CRS, sleep timing, and mood-energy signals. It is not intended to diagnose, treat, cure, or prevent disease, and it should not be used as a substitute for professional medical advice.
Optional connections stay optional
Health Connect, motion or light sensors, CRS platform sync, and exports only affect your data flow if you choose to turn them on.

1. Information BioClock may process
Depending on the features you enable, BioClock may process wellbeing-related information such as bedtime, wake time, sleep quality, fatigue, stress, alertness, energy, mood, calm-tension, mental clarity, perceived jet lag, and local trend summaries.
- Manual wellbeing and sleep inputs
- Locally generated trend data, reminders, alarms, widgets, and settings
- Optional device sensor signals such as light and motion
- Optional Health Connect data such as sleep sessions, heart rate, and activity summaries
- Optional export files you generate yourself
- Optional sync information if you connect an external service such as CRS
2. How BioClock uses data
BioClock uses enabled data sources to estimate BioTime, circadian phase, rhythm alignment, sleep pressure, suggested bedtime, mood-energy patterns, and trend summaries. It also uses local settings to run alarms, notifications, widgets, and reminders in a calm, wellbeing-oriented way.
3. Local-first processing
BioClock is designed to work primarily on-device. Core calculations and stored history are intended to remain local to the device unless you explicitly choose an export or external sync action.
4. When data may leave your device
Your data is not transmitted off-device unless you intentionally use a feature that requires it.
- Exporting CSV, JSON, wellbeing summaries, or clinician-support summaries
- Connecting optional external sync such as CRS platform sync
- Checking for app updates from the BioClock update page
If you enable an optional sync feature, the data used for that feature may be transmitted to the connected service according to that service's own configuration and policies.
5. Data sharing and advertising
BioClock is not designed to sell personal data or use health-related data for advertising. Optional external sharing only happens when you choose actions like export or sync.
6. Permissions
BioClock may request optional permissions such as notifications, alarms, activity recognition, sensor access, and Health Connect access. These permissions support features you choose to enable and can be revoked through Android settings.
7. Retention and deletion
Local BioClock data remains on your device until you delete it, reset the app, or remove it by uninstalling. If you use an external sync service, copies stored there may be retained according to that service's own rules.
8. Security
BioClock aims to minimize data movement and keep wellbeing information local wherever possible. Even so, no device, storage method, or transmission path can be guaranteed to be completely secure.
9. Children
BioClock is not directed to children under 13 for unsupervised use.
10. Your choices
- Use BioClock offline
- Choose which optional sources and integrations are enabled
- Disconnect optional integrations such as Health Connect or CRS sync
- Export local data when you want
- Reset local data from within the app
11. Health and non-diagnostic framing
BioClock presents informational estimates about rhythm, sleep timing, mood-energy pattern, and stability. It is not a medical device, psychiatric evaluator, or source of clinical certainty. Any clinician-facing summary is intended as observational support only.
12. Changes to this policy
This privacy policy may be updated over time. The latest version will be published on this page.
