Privacy Policy
ARC Labs ("we," "our," or "us") operates the Arc Labs Calc mobile application (the "App"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App.
1. No Data Collection
Arc Labs Calc does not collect, store, or transmit any personal information. The App operates entirely on your device. Specifically:
- We do not collect names, email addresses, or account credentials
- We do not track your location
- We do not use analytics, crash reporting, or telemetry SDKs
- We do not serve advertisements or use advertising identifiers
- We do not share data with third parties — because we don't have any to share
2. On-Device Processing
All calculations, including AI-powered watering advice via the integrated Llama 3.2 language model, run entirely on your device. No data is sent to external servers for processing. The AI model operates locally and never transmits your inputs, grow data, or results to ARC Labs or any third party.
3. Data Stored on Your Device
The App stores the following data locally on your device using standard app storage:
- App preferences — theme selection (dark/light), crop steering toggle state
- Calculation history — your last 7 days of watering calculations for quick recall
- AI model files — the Llama 3.2 3B model (~2GB) if you choose to download it
All of this data stays on your device. You can clear it at any time via the "Reset All Settings" option in the App, or by uninstalling the App.
4. Feedback & Email
The App includes an optional feedback feature that opens your device's email client to send bug reports or feature suggestions to info@arclabcanna.com. When you use this feature:
- Bug reports automatically include your device model, OS version, and App version to help us diagnose issues
- You control what is sent — you can review and edit the email before sending
- No data is sent without your explicit action (you must press "Send" in your email app)
5. Children's Privacy
The App is not intended for use by anyone under the age of 18. We do not knowingly collect personal information from children.
6. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
