At Checkoff, we are committed to protecting your privacy and ensuring the security of your data. This Privacy Policy explains how we collect, use, and safeguard your personal information when you use the Checkoff Todo App ("App"). By using the App, you agree to the terms outlined in this policy.
1. Data Collection
1.1 Personal Information
Checkoff collects minimal personal information to provide our services. The only data we collect and know about you are:
- Username: Used for account creation and identification within the App.
- Payment Information: If you choose to make a purchase, we collect only the necessary details to process your payment, such as billing information.
We do not have access to any of the tasks, notes, or other information you store within the App due to the use of zero-knowledge encryption (explained below).
1.2 Usage Data
We may collect anonymized usage data, such as app performance metrics and device information, to improve the functionality and user experience of the App. This information cannot be linked back to any individual user.
2. Data Encryption and Security
2.1 Zero Knowledge Encryption
All of your tasks, notes, and any other data you store in the App are protected using zero-knowledge encryption. This means that:
- Data Encryption: Your data is encrypted both at rest and in transit using industry-standard encryption (AES-256).
- Zero Knowledge: We cannot access, view, or decrypt your notes, tasks, or any other stored content. Only you, the user, have the decryption keys required to access this data.
Even our system administrators cannot read or access your encrypted data. Only your username and payment information are stored unencrypted.
2.2 Authentication
We use secure authentication protocols to ensure that only authorized users can access their accounts. It is your responsibility to keep your password and other authentication credentials safe and secure.
2.3 Data Retention
We retain your username and payment information for as long as necessary to provide the services or as required by law. You can delete your account and all associated encrypted data at any time through the App. Once deleted, the data cannot be recovered.
3. Data Sharing
3.1 Third-Party Service Providers
We may use trusted third-party service providers to assist with hosting, payment processing, and other operational services. These providers are obligated to comply with our strict data protection standards and cannot access or use your encrypted data. They will only process your payment information when necessary to complete a transaction.
3.2 Legal Compliance
We may be required to disclose personal information to comply with legal obligations, such as government requests. However, due to zero-knowledge encryption, we are unable to provide access to any of your tasks, notes, or other encrypted data.
4. User Control Over Data
4.1 Data Access and Deletion
You have complete control over your data:
- Access: You can view, manage, and delete your tasks and notes within the App.
- Deletion: You may permanently delete your account, along with all associated encrypted data, at any time. Once deleted, the data cannot be recovered.
4.2 Portability
Upon request, we can provide you with a copy of your data in a commonly used format. However, please note that since your tasks and notes are encrypted, only you can decrypt the exported data.
5. Children's Privacy
The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children. If we discover that a child under 13 has provided us with personal information, we will delete it immediately.
6. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Any changes will be reflected by updating the date at the top of this policy. If we make significant changes, we will notify you through the App or via email. Your continued use of the App after any changes signifies your acceptance of the updated Privacy Policy.
