Terms of Service

Last updated: 7 November 2026 · Service provider: Lunify Yazılım ve Ticaret A.Ş. · Product: Qaderno (pen-and-paper digital planner)

1. Parties and scope

These terms govern the use of the Qaderno service provided by Lunify Yazılım ve Ticaret A.Ş. (“Lunify”) at qaderno.lunify.world and in the Qaderno Android app. By creating an account or using the service you accept these terms.

2. The service

Qaderno is a digital planner you write in with a pen or your finger: a page for every day, a year calendar, to-dos, page titles, tags and backgrounds, saved automatically and available on all your devices. Optional features can turn your handwriting into text, summarise a day and suggest to-dos with AI, and connect Google Calendar and Google Tasks. The service is provided “as is”; features may be improved or changed over time. Reasonable notice is given before planned maintenance.

3. Account and user responsibility

• You are responsible for keeping your sign-in details confidential and for actions taken from your account.
• You confirm that you have the right to write down and store the content you enter, including any personal data of other people, and that you use it lawfully.
• You may not use the service for unlawful purposes or in a way that infringes the rights of third parties.
• Testing the security of the system without permission, reverse engineering or copying the source code is prohibited.

4. AI features

• AI features run only when you ask for them (for example “transcribe” or “summarise”). The page image or text is then sent to the AI providers listed in the Privacy Notice.
• AI output is a suggestion and may be inaccurate or incomplete; check it before you rely on it.
• Your content is not used by Lunify to train AI models.

5. Google Calendar and Tasks

Connecting Google is optional. Qaderno uses Google data only to show and create calendar events and to sync your to-dos, as described in the Privacy Notice and in line with Google’s Limited Use requirements. You can disconnect at any time in Qaderno Settings or in your Google Account permissions.

6. Fees

Qaderno is currently offered with a free account: no credit card is required. If paid plans are introduced later, prices and billing terms will be shown before you buy, and nothing will be charged without your approval.

7. Ownership of content and backups

Your pages, handwriting and to-dos remain yours; you grant Lunify only the rights needed to store, process and display them to provide the service. On request, a copy of your data is provided within a reasonable time. Lunify takes regular backups, but we recommend keeping your own copy of anything critical.

8. Termination

You can delete your account at any time in Settings; your account and pages are then deleted as described in the Privacy Notice. In case of a clear breach of these terms Lunify may suspend or terminate the account.

9. Limitation of liability

The service is not guaranteed to be uninterrupted or error-free. Lunify’s total liability is limited to the fees you paid for the service in the 12 months before the event. Indirect damages, loss of profit and damages arising from loss of data are excluded. Mandatory consumer rights are reserved.

10. Changes

These terms may be updated. Significant changes are announced in the app or by email; continuing to use the service after the announcement means you accept them.

11. Governing law and contact

These terms are governed by the laws of the Republic of Türkiye; the courts of Istanbul have jurisdiction, without prejudice to mandatory consumer rules.
