Terms of use
Last updated: 11 August 2026
About these terms
These terms govern your use of Kartella Lash, provided by freetokyo apps ("we").
What the app is
The app is a tool for keeping records of treatments. It does not decide whether a treatment is appropriate, and it does not advise on allergy, legal or insurance requirements. Patch test rules and validity periods are set by you; we do not warrant that any particular setting is correct.
Licensing, registration and hygiene requirements differ by region. Please check the primary sources: your local authority, your insurer, and the product manufacturer.
Pricing and purchases
The app is free to start, with some limits (such as 20 clients). To remove those limits and unlock the remaining features, you may purchase either:
- A one-time purchase (non-consumable): paid once, never renewed.
- A yearly plan (auto-renewing subscription), on the terms below.
Auto-renewal terms
- The subscription period is one year. It renews automatically unless you turn auto-renewal off at least 24 hours before the end of the current period.
- Your Apple Account is charged for renewal within 24 hours before the end of the period.
- You can manage or cancel the subscription in your App Store account settings after purchase.
- Payment is charged to your Apple Account at confirmation of purchase.
- Refunds follow Apple's policies; we cannot issue refunds directly.
If a yearly plan lapses, the records you already made stay on your device and remain readable, editable and exportable, and you can still add treatments and delete records. Only three things stop: adding clients beyond 20, retention analysis, and backup export.
Use of the app is subject to Apple's standard End User License Agreement.
Restrictions
You may not reverse engineer the app, use it for unlawful purposes, or use it in a way that infringes the rights of others.
Limitation of liability
We do not warrant that the app is fit for any particular purpose, that records are complete and accurate, or that it will be available without interruption.
Except in cases of our wilful misconduct or gross negligence, our liability is limited to the amount you paid for the app.
To the extent that applicable mandatory law does not allow such a limitation, the limitation applies only so far as the law permits.
Records are stored on your device. We are not responsible for records lost through loss, failure or reset of the device. Please use the backup export.
Changes
We may change these terms. Changes take effect when published on this page.

Limitation of liability (overriding)
Notwithstanding any other provision of these terms, Except in cases of our willful misconduct or gross negligence, our liability for any damages arising from your use of the app is limited to the amount you paid us for the app. Where such a limitation is not permitted by mandatory law, we are liable to the extent that law provides.
