Metryst Terms of Use

Last updated October 10, 2026

Metryst is provided by Cladose LLC, an Illinois limited liability company ("Cladose", "we", "us"). Your use of Metryst is governed by Apple's Licensed Application End User License Agreement (the "Apple EULA") and by these Terms. If they conflict, these Terms apply to the extent the Apple EULA allows. By using Metryst you agree to both.

In these Terms, "records" means the Events (intimate encounter records), Periods (menstrual period records), unavailable dates and timeline markers you create in Metryst, including their details, answers and notes, and any of these a linked partner sends you that you accept.

Adults only

You must be at least 18 years old to use Metryst.

Your account and your records

• You need to sign in with Apple to use Metryst. Keep your iPhone and Apple Account secure.
• Your records belong to you. You give Cladose permission to store, process and transmit them only as needed to provide Metryst, as described in our Privacy Policy and Consumer Health Data Privacy Policy.
• You can export or delete your data at any time in Settings.

Partners and sharing

• Linking with a partner is optional and requires both of you to agree. Nothing is sent to a partner unless you choose to send it.
• Metryst has no messaging, chat, profiles, search or directory, and no way to contact someone who has not linked with you. A linked partner sees only your name as you entered it, whether your Premium covers them, the status of items you send, and the records you choose to send. They cannot see your email address, your account details, or any record you have not sent.
• When your partner accepts something you send, they keep their own copy. You cannot remotely delete or change their copy, and they cannot change yours.
• Only record and send information you have the right to share, and respect your partner's privacy. Do not use Metryst to record or share information about anyone under 18, or to harass, threaten, monitor or control another person.

Premium subscriptions

• Metryst is free to download, and the free version stays available. Premium is an optional auto-renewing subscription sold by Apple, billed monthly or yearly at the price shown in the app before you buy.
• One Premium subscription covers you and the one partner your account is linked with, for as long as you stay linked. If the link ends, Premium continues only for the person who subscribed.
• New accounts get a 7-day Premium Preview automatically. It does not start a subscription and does not charge you.
• Eligible new users may be offered a free trial. If you start one, it converts to a paid subscription at the end of the trial unless you cancel at least 24 hours before it ends.
• Payment is charged to your Apple Account. Subscriptions renew automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel in your Apple Account settings, under Subscriptions.
• Refunds are handled by Apple under its policies.
• Deleting your Metryst account does not cancel an Apple subscription.

Not medical advice

Metryst is a personal record-keeping and insights app. Period forecasts and other insights are estimates based on what you record. They are not medical advice, diagnosis or treatment, and must not be used for contraception or to plan or prevent pregnancy. Talk to a healthcare professional about medical questions.

Acceptable use

Do not misuse Metryst. That includes trying to access other people's accounts or data, interfering with the service, reverse engineering it except where the law allows, or using it for anything unlawful. We may suspend or close accounts that do.

Availability and changes

We work to keep Metryst available and your data safe, but we cannot promise the service will always be uninterrupted or error-free. Keep your own exports of anything you cannot afford to lose. We may change Metryst and these Terms; if we make a material change to these Terms, we will tell you in the app before it takes effect.

Liability

The Apple EULA's warranty disclaimer and limitation of liability apply to Metryst. Nothing in these Terms limits rights you have under laws that cannot be waived.

Governing law

These Terms are governed by the laws of the State of Illinois, without regard to its conflict-of-law rules. Any dispute about these Terms or Metryst will be resolved in the state or federal courts located in Illinois, except where the law of your state gives you the right to bring a claim where you live.
