Terms of Service
1. Acceptance of Terms
Welcome to One Calendar! These Terms of Service ("Terms") govern your access to and use of the One Calendar mobile application (the "App") and our website at onecalendar.win (the "Website").
By downloading, installing, or using One Calendar, you agree to be bound by these Terms and our Privacy Policy. If you do not agree to these Terms, please do not use the App.
These Terms constitute a legally binding agreement between you ("you" or "User") and One Calendar ("we," "us," or "our").
2. Description of Service

- Create, view, edit, and delete events and reminders
- View your calendar in Day, Week, Month, and Year formats
- Set up recurring events and customizable reminders
- Receive local notification alerts for scheduled reminders
- Store all data locally on your device with no cloud synchronization
The App is provided free of charge with no advertisements, in-app purchases, or subscription fees.
3. License and Restrictions
3.1 License Grant
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the App on devices that you own or control, solely for your personal, non-commercial use.
3.2 Restrictions
You agree NOT to:
- Modify, reverse engineer, decompile, or disassemble the App

- Use the App for any illegal or unauthorized purpose
- Distribute, sublicense, rent, lease, or lend the App to third parties

- Use the App in any manner that could damage, disable, overburden, or impair the App
- Attempt to gain unauthorized access to any portion of the App or its related systems
- Use automated scripts, bots, or other automated means to interact with the App
4. User Responsibilities
4.1 Device and Permissions
You are responsible for:
- Maintaining a compatible device and operating system to run the App
- Granting necessary system permissions (notifications, alarms) for the App to function properly
- Keeping your device secure with passwords, biometric locks, and other security measures
- Installing operating system updates and security patches
4.2 Data Backup
Because all data is stored locally on your device, you are solely responsible for backing up your calendar data. We recommend periodically backing up your device or using any future export features we may provide. We cannot recover data that is lost or deleted.
4.3 Appropriate Use
You agree to use One Calendar only for lawful purposes and in accordance with these Terms. You will not use the App to store, organize, or schedule any illegal activities.
5. Intellectual Property
All intellectual property rights in the App, including but not limited to software code, design, graphics, text, and trademarks, are owned by or licensed to us.
The "One Calendar" name and logo are trademarks. You may not use these trademarks without our prior written permission.
Your calendar data (events, reminders, etc.) remains your property at all times. We do not claim any ownership rights to your data.
6. Privacy and Data
Your privacy is extremely important to us. Please review our Privacy Policy to understand how we handle your information.
Key points:
- We do not collect, store, or transmit your personal data or calendar information
- All data is stored locally on your device
- We have no access to your events, reminders, or any other data you create in the App
7. Disclaimer of Warranties
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED.
To the fullest extent permitted by law, we disclaim all warranties, including but not limited to:
- Implied warranties of merchantability, fitness for a particular purpose, and non-infringement
- Warranties that the App will be uninterrupted, error-free, or free of viruses or other harmful components
- Warranties regarding the accuracy, reliability, or completeness of any information or content in the App
- Warranties that defects will be corrected or that the App will meet your requirements
Some jurisdictions do not allow the exclusion of implied warranties, so some of the above exclusions may not apply to you.
Important: While we strive to provide reliable reminder notifications, we cannot guarantee that all notifications will be delivered on time or at all due to factors outside our control (device power state, OS limitations, system settings, etc.). Do not rely solely on One Calendar for critical time-sensitive reminders (e.g., medication, flight departures).
8. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR USE.
This includes but is not limited to damages arising from:
- Your use of or inability to use the App
- Loss of data, including calendar events and reminders
- Missed appointments, meetings, or events due to notification failures
- Device malfunctions or data corruption
- Unauthorized access to your device or data by third parties
- Errors, bugs, or inaccuracies in the App
Our total aggregate liability for any claims arising from or relating to these Terms or the App shall not exceed the amount you paid us for the App. Since the App is free, this means our total liability is $0 USD.
Some jurisdictions do not allow the limitation or exclusion of liability for incidental or consequential damages, so the above limitations may not apply to you.
9. Indemnification
You agree to indemnify, defend, and hold harmless One Calendar and its affiliates, officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, costs, or expenses (including reasonable attorneys' fees) arising out of or relating to:
