1. Information We Collect
Depending on how you use OncoBond, we may collect the following categories of information:
- Account information: Email address and/or mobile number, account identifier, and information needed to create and manage your account.
- Profile information: Information you choose to provide in your profile.
- Content you share: Posts, comments, private messages, images, and other content you submit or share through OncoBond.
- Technical and performance information: Device and app information, usage information, and app performance or diagnostic information. Firebase Performance Monitoring is enabled and may collect performance information such as app response times and technical performance data.
- Android registration-event information: When an account is created through the Android app, OncoBond sends a CompleteRegistration event to Meta using the Meta Conversions API. The information sent may include a SHA-256-hashed email address, a UID-derived event ID, platform and action-source information, IP address, and user-agent information.
OncoBond does not send this Meta registration event from the iOS app.
Because OncoBond is a cancer support community, content you choose to share may reveal information about your health or cancer-related experiences. Depending on applicable law, this may constitute sensitive personal data or health-related data.
2. How We Use Information
We use information for purposes including:
- Creating, authenticating, and managing accounts.
- Providing, operating, maintaining, and securing OncoBond.
- Enabling users to communicate through posts, comments, private messages, and images.
- Storing, displaying, transmitting, and delivering content shared through the platform.
- Communicating with users about their accounts and the platform.
- Reviewing reports, moderating content, preventing misuse, and enforcing our Terms of Use and Community Guidelines.
- Monitoring app performance and identifying technical issues through Firebase Performance Monitoring.
- Measuring and optimizing advertising campaigns and attributing Android registrations to advertising campaigns through Meta.
We do not sell your personal information. We may disclose information to service providers and other recipients where necessary to operate the platform, provide requested services, measure advertising campaigns, comply with legal obligations, or protect the rights and security of users and OncoBond.
3. Service Providers and Third-Party Services
We use third-party service providers to help operate and maintain OncoBond. These providers may process information on our behalf or in accordance with their own applicable privacy terms.
Google Firebase
We use Google Firebase services for platform infrastructure, which may include hosting, authentication, and database services. Firebase Performance Monitoring is enabled and is used to collect app performance information that helps us understand and troubleshoot technical performance issues.
Firebase Crashlytics is currently turned off and is not used by OncoBond as described in this policy.
Meta Conversions API — Android only
When a user creates an account through the Android app, OncoBond sends a CompleteRegistration event to Meta using the Meta Conversions API. This event may be used to measure, attribute, and optimize advertising campaigns promoting the OncoBond app.
The information sent with this event includes a SHA-256-hashed email address, a UID-derived event ID, platform and action-source information, IP address, and user-agent information. The email address is hashed before it is sent to Meta.
This registration event is sent from Android only. OncoBond does not send this event from the iOS app.
Meta may process information it receives in accordance with its own policies and terms. For more information, consult Meta's Privacy Policy .
4. Advertising and Advertising Measurement
OncoBond may use Meta advertising technologies to measure and optimize advertising campaigns promoting the app.
As described above, when an account is created through Android, OncoBond sends a CompleteRegistration event to Meta. This event may include a SHA-256-hashed email address, a UID-derived event ID, platform and action-source information, IP address, and user-agent information. The event is not sent from iOS.
This information may be used for advertising measurement, attribution, and campaign optimization. Meta may process the information under its own privacy terms.
Where required by applicable law, we will obtain consent or provide choices before processing or sharing personal information for advertising purposes. Depending on your location and applicable law, you may have rights to object to or restrict certain advertising-related processing.
5. Photos, Camera, and Shared Content
To let you upload photos, OncoBond requires permission to access photos you select from your photo library.
OncoBond does not use or access your camera anywhere in the app.
Content shared in community areas may be visible to other users. Private messages are intended for communication between the participants, but should not be treated as confidential or guaranteed to remain private. Recipients may copy, save, or share content outside OncoBond.
6. Account and Content Deletion
You can delete your OncoBond account. You can also delete your posts, comments, and chats where those deletion options are available.
We recommend deleting any posts, comments, or chats you no longer want available before deleting your account, where those options are available.
When you delete a chat, it is removed from the views of both participants. Deleting content from OncoBond may not remove copies that another user previously saved, copied, or shared outside the platform.
When you delete your account or content, we will delete or anonymize the relevant personal information as applicable, subject to technical limitations and any information we are required or permitted to retain for legal compliance, security, fraud prevention, dispute resolution, or other lawful purposes.
Any information retained will continue to be handled in accordance with this Privacy Policy and applicable law.
7. International Data Transfers
OncoBond and its service providers may process or store information in countries other than the country where you live. Where applicable law requires safeguards for international transfers, we will use appropriate safeguards for those transfers.
8. Data Retention
We retain personal information for as long as reasonably necessary to provide and maintain the platform, fulfill the purposes described in this policy, comply with legal obligations, resolve disputes, and protect the security of OncoBond and its users.
Retention periods may vary depending on the type of information, the purpose for which it is processed, and applicable legal requirements. When information is no longer needed, we will delete or anonymize it as appropriate.

Depending on your location and applicable data protection laws, you may have the right to:
- Request access to your personal information.
- Request correction of inaccurate or incomplete information.
- Request deletion of your personal information.
- Request portability of certain information.
