Privacy Policy

Last updated: June 2, 2026

ARC Labs ("we," "our," or "us") operates the ARC Labs Calc web calculator (the "Tool"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our Tool.

1. No Data Collection

ARC Labs Calc does not collect, store, or transmit any personal information. The Tool runs entirely in your web browser. 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. Client-Side Processing

All calculations run entirely in your browser. No data is sent to external servers for processing. Your inputs, grow data, and results never leave your device.

3. Data Stored in Your Browser

The Tool stores the following data locally in your browser using standard browser storage:

Tool preferences — theme selection (dark/light), crop steering toggle state
Calculation history — your last 7 days of watering calculations for quick recall

All of this data stays in your browser. You can clear it at any time via your browser's settings, or by clearing site data for arclabcanna.com.

4. Feedback & Email

The Tool 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 browser and OS 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 Tool 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.
