This Privacy Policy explains how Period Tracker Ovulation Bloom ("Bloom", "we", "us", or "our") collects, uses, stores, and protects information when you use the Bloom mobile application.
By using Bloom, you agree to the practices described in this Privacy Policy.
Bloom may collect or process information that you provide when using the app, depending on the features you choose to use.
When you use Bloom's cycle tracking features, you may provide information such as:
This information is used to provide features such as period tracking, cycle history, predicted periods, fertile-window estimates, and estimated ovulation timing.
If you use cloud synchronization or account-based features, Bloom may process information associated with your account, such as:
Bloom provides an optional partner-sharing feature. If you choose to use this feature, the app may process information required to create or use a sharing code and provide access to selected cycle information.
Partner sharing is optional. You should only share your information with people you trust.
Depending on the services enabled in the app, certain technical information may be collected automatically, such as:
We may use information to:
Bloom stores and processes certain cycle information to provide its core tracking and calendar features.
Depending on the features you use, this may include:
Your current period information and cycle settings may be synchronized with our cloud services, including Firebase, even when Partner Mode is not enabled. This synchronization allows your cycle information and settings to remain available across supported app sessions and devices and helps provide the app's core functionality.
Bloom uses Google Firebase and related services to provide certain application functionality, including account authentication, cloud data storage, synchronization, and other technical services.
When you use Bloom, information such as your current period and cycle settings may be stored in Firebase. This can occur regardless of whether you enable Partner Mode.
Firebase may process information associated with your Bloom account, including a user identifier and the cycle information that you choose to store or synchronize through the application.
Firebase is operated by Google. Information processed through Firebase is subject to Google's applicable privacy policies and security practices.
Bloom includes an optional Partner Mode that allows you to share certain cycle information with a partner.
Partner Mode is separate from the normal synchronization of your Bloom data. Your current period and cycle settings may already be synchronized with Firebase even if you never enable Partner Mode.
If you choose to use Partner Mode, additional information may be made available to the partner you authorize through the sharing feature.
Partner sharing is optional. You should only enable this feature and share your cycle information with people you trust.
We do not sell your personal information.
Bloom may share or provide access to information with service providers when necessary to operate the application. For example, Firebase may process and store your current period and cycle settings to provide synchronization and other app functionality.
If you voluntarily enable Partner Mode, selected cycle information may also be shared with the partner you authorize through the application's sharing functionality.
We may also disclose information where required by applicable law, regulation, legal process, or valid governmental request.
Cycle information synchronized with Firebase may remain associated with your Bloom account while you use the application's cloud-enabled features.
You may delete or modify available cycle information through the application where those controls are provided. If you want to request deletion of your cloud-stored account information, contact us using the email address provided in this Privacy Policy.
Some information may be retained where required by law or where reasonably necessary for security, fraud prevention, dispute resolution, or other legitimate purposes.
If cloud synchronization or partner-sharing features are enabled, relevant information may be transmitted to and stored by third-party cloud service providers used by Bloom.
Bloom may use services such as Google Firebase to provide authentication, database storage, synchronization, crash reporting, analytics, and other technical services.
These providers process information according to their own privacy policies and applicable terms.
Bloom may display advertisements through third-party advertising providers. If advertising is enabled, these providers may collect information such as advertising identifiers, device information, approximate location, and information about ad interactions, subject to their own policies and your applicable device or consent settings.
We do not provide advertisers with your personal period history for the purpose of displaying advertisements.
Bloom may use analytics services to understand how users interact with the application and to improve stability and functionality.
Analytics information may include app interactions, device information, app version, crash information, and other technical or usage information.
Bloom may use third-party service providers to operate certain features. Depending on the version and features enabled, these may include:
Third-party services may collect and process information according to their respective privacy policies.
We do not sell your personal information.
Information may be shared with service providers only when reasonably necessary to operate, maintain, secure, or improve Bloom and its features.
If you voluntarily use the partner-sharing feature, selected cycle information may be made available to the person you authorize through that feature.
We may also disclose information where required by applicable law, regulation, legal process, or valid governmental request.
We take reasonable measures to protect information processed through Bloom against unauthorized access, alteration, disclosure, or destruction.
However, no method of electronic transmission or storage is completely secure, and we cannot guarantee absolute security.
We retain information only for as long as reasonably necessary to provide the requested features, maintain our services, comply with legal obligations, resolve disputes, and enforce our agreements.
Information stored locally on your device may remain there until you delete the information, uninstall Bloom, or otherwise remove the app's stored data.
Depending on the features you use, you may be able to:
If Bloom provides account-based cloud storage, you may request deletion of your account and associated cloud data by contacting us using the email address below.
Some information may be retained where required by law or where reasonably necessary for legitimate security, fraud prevention, or legal purposes.
Bloom is not intended for children under the applicable minimum age required by the laws of their country or region.
We do not knowingly collect personal information from children in violation of applicable laws. If you believe that a child has provided personal information to us, please contact us so that we can take appropriate action.
Depending on the services used by Bloom and the location of our service providers, information may be processed or stored in countries other than your country of residence.
Where required, appropriate safeguards will be used in accordance with applicable privacy laws.
We may update this Privacy Policy from time to time to reflect changes in Bloom, our services, or applicable legal requirements.
When changes are made, we will update the "Last updated" date at the top of this Privacy Policy.
If you have questions, concerns, or requests regarding this Privacy Policy or your information, please contact us:
