2. Information We Collect

5. Advertising and Third-Party Content

Our Service may contain advertisements and links to third-party websites, applications, or services. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites or services. We strongly advise you to review the privacy policy of any third-party sites or services that you visit or interact with through our app.

Third-party advertisers may use cookies, web beacons, or other tracking technologies to collect information about your use of our Service and other applications to provide advertisements that may be of interest to you.

6. Data Security

The security of your data is important to us. Since 1664 works offline and stores data locally on your device, your personal information never leaves your device unless you explicitly choose to share it.

We implement appropriate technical and organizational security measures to protect your information against unauthorized access, alteration, disclosure, or destruction. However, please remember that no method of transmission over the internet or method of electronic storage is 100% secure.

7. Data Retention

All your personal data (cleaning schedules, tasks, room configurations) is stored locally on your device and is retained until you choose to delete it or uninstall the app.

Any anonymous usage data we collect may be retained for a reasonable period necessary to fulfill the purposes outlined in this Privacy Policy, unless a longer retention period is required or permitted by law.

8. Your Rights and Choices

You have several rights regarding your information:

• Access: You can access all your data directly within the app
• Deletion: You can delete any data by using the app's delete functions or uninstalling the app
• Portability: Your data is stored in standard formats on your device
• Opt-out: You can opt-out of analytics through your device settings

9. Children's Privacy

Our Service is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we discover that a child under 13 has provided us with personal information, we will delete such information immediately.

If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us so that we can take necessary action.

10. International Data Transfers

Since 1664 works offline and stores data locally, your personal information is not transferred internationally. Any anonymous analytics data may be processed in different countries, but this data cannot be used to identify you personally.

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "last updated" date at the top of this Privacy Policy.
