Terms of use

Short, because the product is small: you get a licence to use the tool and the report it produces for your own aircraft. It does not come with a promise that the tune is right for your aircraft. Nothing here reduces rights you have under mandatory consumer law.

The service

Easyquadtune analyses a Betaflight blackbox log and produces a report and a suggested CLI change. The output is derived from the log you supply and the profile you select. Analysis may run on your device or on a server, depending on the build and the file.

Licence

A purchased licence covers the number of logs stated at checkout for the person who bought it.
The key is intended for the buyer's own use on their own machines. Sharing a key to avoid payment is not permitted.
There is no account. The key is stored on the device; losing the device does not lose the purchase, and the key can be requested again at the checkout email address.
Prices and plans are those shown at checkout: the first log is free, then $2.99 per log, $9.99 per month or $79.99 per year.

Your responsibilities

Fly the verification flight. Apply changes one step at a time, check motor temperature, and re-log. A report is a hypothesis until the aircraft confirms it.
Check before you paste. The CLI block targets the firmware and header in your log. If you changed firmware or hardware since that flight, the values may not transfer.
Keep your own copy of the log and the report. The service does not archive them for you.
Do not upload a log you have no right to share, or one containing another person's personal data.

No warranty on the tune

The analysis is provided as-is. To the extent permitted by law, no warranty is given that a suggested change will improve handling, and the author is not liable for damage to an aircraft, property or persons arising from applying a suggestion. This is not a limitation of liability for death, personal injury caused by negligence, fraud, or any liability that cannot lawfully be excluded.

Availability and changes

The tool may change, and measurement code is improved when it is found to be wrong. When a change alters a number, the changelog says so. Features are not promised to remain identical, but a purchased log entitlement is not removed by a code change.

Acceptable use

No attempt to extract the tuning recipe for redistribution, or to bypass the licence check.
No automated bulk uploading that degrades the service for others.
No using the service to break the law or to process data you do not have permission to process.

Governing terms and contact

These terms are governed by the law of the seller's country of establishment, without affecting mandatory consumer protections in your country of residence. Questions about a purchase or these terms: easyquadtune@outlook.com.
