Terms of Use
Kartella
Last updated: 9 August 2026
Scope
These terms set out the conditions for using Kartella ("the app"). By using the app you are taken to have agreed to them.
What the app is
The app is a tool for storing, showing and exporting records that you enter yourself. It does none of the following:
- Guarantee compliance with any law, regulation or industry standard
- Promise that the requirements of an insurance policy are met
- Prevent allergic reactions, decide whether a service should go ahead, or give medical or professional advice
- Guarantee any legal effect for a signature
- Make age-related legal judgements about clients under the age of majority
How and how often to patch test, and whether to carry out a service, are for you to decide with the product instructions and, where needed, a qualified professional.
Your clients' information
Most of what is recorded in the app concerns your clients. Responsibility for obtaining, holding, disclosing and deleting that information rests with you; the developer has no access to it.
The app provides features for responding to such requests (exporting one client's records as a PDF, deleting identifying details only, or deleting everything), but it does not judge which response is appropriate. Deletion cannot be undone.
Purchases
Full access is a one-time in-app purchase, not an auto-renewing subscription. It is tied to your Apple Account and can be restored with the same account. Refunds follow Apple's policy and should be requested from Apple directly.
Within the free tier you can always read, edit, export and delete records you have already made.
Looking after your data
Records are stored only on your device. The developer has no way to recover data lost through a lost, broken or erased device, deletion of the app, or a forgotten backup password. Please use the backup export feature. Backup passwords are not stored in the app, so a forgotten password means the file cannot be restored.
What you may not do
Do not use the app for unlawful purposes, copy, modify or reverse-engineer it, or use it in a way that infringes the rights of others.
Liability
The developer is not liable for loss arising from use of the app, except where caused by the developer's intent or gross negligence. Where mandatory law does not permit liability to be excluded, the excluding provision does not apply and liability is accepted to the extent the law requires.
Changes to these terms
These terms may be changed from time to time. A change takes effect when it is 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.
