Privacy Policy

Privacy Policy

Last Updated: 12 September 2026

This Privacy Policy describes how PhaseMate LLC ("PhaseMate," "we," "us," or "our") collects, uses, shares, and protects personal information when you use our mobile application and website (together, the "Service").

PhaseMate is a menstrual cycle tracking application for individuals and couples. Because the Service handles information about reproductive health, we have written this policy to be specific about what we collect, who we share it with, and what we deliberately do not collect.

By using the Service, you agree to the terms outlined in this Privacy Policy.

1. What We Deliberately Do Not Collect

We designed the Service to hold as little identifying information as possible. We do not collect:

  • Your name. We do not ask for your real name, your partner's name, or any display name at signup or at any point afterwards.
  • Your phone number.
  • Your address.
  • Your precise location. We do not request or use GPS.
  • Your payment card details. These are handled entirely by Apple, Google, or Stripe and never reach us.

This is a deliberate design choice, not an oversight. Less collected means less at risk.

2. Information We Collect

Account information

When you create an account, we collect your email address and authentication identifiers. If you sign in using Apple, we receive the identifier Apple provides, which may be a private relay email address.

Health and cycle information

This is the core data the Service is built around. Depending on which features you use, we may collect:

  • Period start and end dates
  • Cycle length and calculated cycle phase
  • Symptoms, moods, and notes you choose to log
  • Your stated goal for using the app (for example, general tracking, trying to conceive, avoiding pregnancy, or reducing relationship friction)

This information is provided by you voluntarily. The Service cannot function without cycle dates.

Partner information

PhaseMate allows two users to link accounts so that one partner can view the other's cycle information. Linking requires an explicit action by both people. If you link with a partner, the partner you link with will be able to see cycle and phase information from your account.

We require that you obtain your partner's consent before linking accounts or using the Service to track another person's cycle. You may unlink at any time.

Purchase information

When you subscribe, we collect your subscription status, plan type, trial status, purchase and renewal dates, and transaction identifiers. We do not collect or store your credit card number, bank details, or other payment credentials — these are handled entirely by Apple, Google, or Stripe, depending on where you subscribe.

Device and usage information

We and the third-party services listed below collect:

  • Device identifiers and advertising identifiers
  • App version, operating system, and device type
  • Push notification tokens
  • In-app activity, such as screens viewed and features used
  • Approximate location (city or region level), derived from your IP address. We do not collect GPS or precise location.
  • Crash and performance diagnostics

3. How We Use Information

We use the information we collect to:

  • Provide cycle tracking, predictions, and phase-based content
  • Enable partner linking and shared cycle visibility
  • Create and manage your account and subscription
  • Send push notifications and emails you have opted into
  • Understand how the app is used so we can improve it
  • Measure the effectiveness of our marketing
  • Detect, prevent, and address technical problems, fraud, or abuse
  • Comply with legal obligations

4. How We Share Information

We do not sell your personal information. We do not share your cycle or health data with advertisers, data brokers, or social media platforms.

We share information with the following categories of service providers, who process it on our behalf and under contract:

Provider What it receives Why
Supabase Cycle data, symptoms, account and partner-link data Database and storage
Google Firebase Authentication identifiers, app diagnostics Sign-in and app infrastructure
RevenueCat Subscription and purchase data, user identifier Subscription management
Mixpanel App activity, device identifiers, approximate location Product analytics
OneSignal Push tokens, device identifiers Push notifications
Klaviyo Email address, subscription status Email communications and marketing
AppsFlyer Device and advertising identifiers, install and event data Marketing attribution
Apple / Google Play / Stripe Payment processing Handling your purchase

We may also disclose information:

  • Where required by law, regulation, legal process, or enforceable governmental request (see Section 5)
  • To protect the rights, property, or safety of PhaseMate, our users, or the public
  • In connection with a merger, acquisition, or sale of assets, in which case we will notify you before your information is transferred and becomes subject to a different privacy policy

5. Government and Legal Requests

We know that people using a cycle tracking app worry about this, so we want to be direct about it.

What we cannot promise. PhaseMate LLC is a US company, and like every company that stores data, we can be compelled by a valid court order, subpoena, or other legally enforceable process to disclose information we hold. No privacy policy can override that, and we will not claim otherwise.

What we commit to. Where we receive a request for user information:

  • We disclose only where we are legally compelled to, and only the specific information the request actually requires — never more.
  • We review every request and will challenge or seek to narrow any request that appears overbroad, improperly issued, or legally invalid.
  • We will notify the affected user before disclosing, unless we are legally prohibited from doing so or there is an emergency involving risk of serious harm.

What limits the risk. As described in Section 1, we do not hold your name, phone number, address, or precise location. Our records are linked to an email address, not to a legal identity.

This is meaningful data minimisation, but it is not anonymity, and you should not treat it as such. An email address is itself an identifier, other parties (such as your email provider or app store) hold information that can connect it to you, and analytics providers hold device identifiers. If you want the strongest possible protection, use an account you do not otherwise use, or delete your account when you no longer need it.

6. Data Security

We protect your information using encryption in transit (TLS/HTTPS for all data transmitted between your device and our servers), encryption at rest, access controls limiting who can access production data, and authentication requirements for account access.

No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

7. Data Retention

We retain your personal information for as long as your account is active or as needed to provide the Service. When you delete your account, we delete your personal information from our active systems, though residual copies may persist in backups for a limited period. We may retain certain information where required by law or for legitimate business purposes such as fraud prevention and financial record-keeping.

8. Your Rights and Choices

You can delete your account and associated data at any time. You may do this from within the app, or by visiting:

https://www.phasemateapp.com/pages/delete-account

If the in-app deletion does not work for any reason, email us at info@phasemateapp.com and we will delete your account manually.

Depending on where you live, you may also have the right to:

  • Access the personal information we hold about you
  • Correct inaccurate information
  • Request deletion of your information
  • Object to or restrict certain processing
  • Receive a copy of your information in a portable format
  • Withdraw consent where processing is based on consent
  • Opt out of marketing emails, using the unsubscribe link in any email we send
  • Disable push notifications in your device settings

To exercise any of these rights, contact us at info@phasemateapp.com. We will respond within the timeframes required by applicable law.

If you are in the European Economic Area or the United Kingdom, you also have the right to lodge a complaint with your local data protection authority.

9. Legal Bases for Processing (EEA and UK Users)

Where the GDPR applies, we process your personal information on the following bases:

  • Consent — for health data, marketing communications, and partner linking. Health data is a special category of personal data under Article 9 GDPR, and we process it on the basis of your explicit consent. You may withdraw consent at any time by deleting your account.
  • Contract — to provide the Service you have signed up for, including subscriptions
  • Legitimate interests — to improve the Service, secure it, and understand how it is used, where those interests are not overridden by your rights
  • Legal obligation — where we are required to retain or disclose information by law

10. International Transfers

PhaseMate LLC is a limited liability company registered in the State of Wyoming, United States, and our service providers operate in the United States and other countries. If you access the Service from outside the United States, your information will be transferred to, stored, and processed in the United States. Where required, we rely on appropriate safeguards such as Standard Contractual Clauses for these transfers.

11. Children's Privacy

PhaseMate is intended for users aged 18 and over. We do not knowingly collect personal information from children under 13. If we learn that we have collected personal information from a child under 13, we will delete it. If you believe a child has provided us with personal information, contact us at info@phasemateapp.com.

12. Health Disclaimer

PhaseMate is a tracking and educational tool. It is not a medical device, and it does not provide medical advice, diagnosis, or treatment. PhaseMate must not be used as a method of contraception or to prevent pregnancy. Cycle predictions are estimates based on the information you enter and may be inaccurate. Always consult a qualified healthcare professional about your health.

13. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last Updated" date at the top of this page. If we make material changes, we will provide additional notice, such as an in-app message or an email. We encourage you to review this policy periodically.
