Version: v1.0 · Effective Date: September 26, 2026 · Operator: Hangzhou Kasoo Labs
Technology Co., Ltd.
1. Introduction
EchoKeep (the "App") is operated by Hangzhou Kasoo Labs Technology Co., Ltd. ("we",
"us"). We take your privacy seriously. This Privacy Policy explains
what information we collect, how we use, store, and protect it, and the
choices you have.
Please read this policy carefully before using the App. By using the App or creating
an account, you acknowledge that you have read and understood this policy.
2. Account Information
When you register or sign in, we collect and store the following through Firebase
Authentication:
-
Your email address (when signing in with Apple, you may choose to
hide your real address and use a private relay address provided by Apple);
-
Your name and profile photo, if you authorize them via Google or
Apple sign-in;
- Sign-in credentials and authentication tokens (used solely to
authenticate you and never disclosed to third parties).
We never read or store your email password in plain text. If you register with
email, your password is securely hashed by Firebase Authentication.
3. Content You Create
To keep your memories in sync across devices, the content you create is stored in
the cloud (Google Cloud Firestore and Firebase Storage, isolated by your account
ID), including:
- The text of your memories and custom notification messages;
- Images you attach to a memory (up to 10MB each);
- Reading and completion records, reminder schedules, and related
settings.
This content belongs to you. We do not use it for any other purpose and we never
sell it to anyone.
4. Product Interaction Data (Optional)
With your consent, we collect anonymous usage data through
Microsoft Clarity to understand how the App is used and to improve it, including:
- Session recordings (page views, taps, and scroll gestures);
- Device and system information (model, OS version, interface
language, etc.);
-
An association with your account ID while you are signed in (for
cross-session analysis).
Clarity automatically masks text input and never records your passwords. We ask for
your consent on first launch, and you can turn this feature on or off at any time in
Settings. When it is off, we collect no analytics data.
5. Local Data
Some data is stored only on your device, including reminder data in a local database
and preferences such as language and reminder toggles. This data is removed when you
clear the App's data or uninstall it.
6. System Permissions
The App only requests permissions that are necessary for its features:
notification permission for local reminders, and
alarm-related permissions to trigger reminders on time.
We do not request sensitive permissions such as microphone, camera,
location, or contacts, and we do not access your photo library — image selection
happens through the system picker, and the App only receives the image you choose.
7. Third-Party Services
The App relies on the following third-party services to process data. These services
process data under their own privacy policies, and your data may be stored on
servers outside your country or region:
- Firebase Authentication / Cloud Firestore / Firebase Storage
(Google LLC): account authentication and cloud data storage;
- Google Sign-In (Google LLC): signing in with Google;
- Sign in with Apple (Apple Inc.): signing in with Apple;
- Microsoft Clarity (Microsoft Corporation): anonymous usage
analytics (optional, can be disabled in Settings);
- Google Fonts (Google LLC): interface font downloads.
8. How We Use Information
The information we collect is used only to:
- Provide core features: account sign-in, cloud sync of your
content, and scheduled reminders;
- Improve the product: analyze anonymous usage data, only with your
consent;
- Maintain security: authenticate users and prevent abuse.
We do not sell your personal information or use it for targeted advertising.
9. Storage and Security
Your data is protected in transit through encrypted connections (HTTPS/TLS). Cloud
data is logically isolated by account ID and accessible only when you are signed in.
We apply reasonable technical and organizational measures to protect your
information, but no security measure can guarantee absolute safety. In the event of
a security incident, we will notify you promptly and take remedial action.
Your data is retained while your account is active. After your account is deleted,
we will delete or anonymize your personal information within 7 business days.
10. Your Rights and Choices
You have the following rights and choices:
- Access and correction: view and edit your content and account
information in the App while signed in;
- Deletion: delete individual memories at any time, or request
account deletion in Settings → Delete Account; we complete deletion within 7
business days;
- Withdraw consent: turn off product interaction data collection at
any time in Settings; deleting your account or uninstalling the App also stops
the corresponding collection;
- Contact us: to exercise these rights or ask questions about this
policy, email [email protected] and we will respond within a reasonable time.
Account deletion permanently removes your account information and cloud content and
cannot be undone.
11. Children's Privacy
The App is not directed at children under 14 (or the equivalent minimum age in your
jurisdiction), and we do not knowingly collect information from children. If you
believe a child has used the App without a guardian's consent, please contact us
and we will delete the relevant information promptly.
12. Policy Updates
We may update this policy from time to time. For material changes, we will notify
you through in-app notices. The version and effective date of this policy appear at
the top. Continued use of the App after an update means you accept the updated
policy.
