Terms of Service

Effective date: 29 June 2026. Last updated: 29 June 2026.

These Terms are the agreement between you and PeriodBro. They cover the marketing site (periodbro.com) and the app (app.periodbro.com). By creating an account, starting a trial, or using either, you agree to what is written here. If you don’t agree, that’s fine, but please don’t use the service.

If you only read one paragraph: PeriodBro is a tool to help you understand and support someone through their cycle. It is not medical advice, it is not a contraceptive, and it doesn’t predict anything with certainty. Be kind with the data you enter about other people, and read section 6 before you do.

1. Who you’re agreeing with

PeriodBro is operated by Devlet Butaev, an independent sole proprietor. Throughout these Terms, “we,” “us,” and “PeriodBro” mean that operator. “You” means the person using the service.

2. What PeriodBro is — and what it isn’t

PeriodBro helps men understand and support the women in their lives — partners, daughters, mothers — through the menstrual cycle. It gives you a place to track cycles, learn what each phase tends to look like, and show up better.

It is an informational and supportive tool, nothing more. PeriodBro is not a medical device, not a diagnostic tool, not a method of contraception or fertility planning, and not a substitute for a doctor. Cycle predictions are estimates based on the data entered, and bodies don’t read the calendar. Don’t make medical, contraceptive, or fertility decisions based on what the app shows you. See section 11.

3. Who can use it

You must be at least 18 years old to create an account and use PeriodBro. By using the service you confirm that you are 18 or older and legally able to enter into this agreement. PeriodBro is not directed at children, and we don’t knowingly let anyone under 18 create an account. See also our Privacy Policy.

4. Your account

You’re responsible for your account and for keeping your login details private. Anything done through your account is treated as done by you. Let us know through our contact form as soon as you suspect someone else has access. Give us accurate information when you sign up, and keep it current.

5. Acceptable use

Use PeriodBro for what it’s for: caring for people in your life. Don’t use it to:

  • track, monitor, surveil, or control anyone without their knowledge or against their wishes;
  • break any law, or anyone’s privacy or other rights;
  • reverse‑engineer, scrape, overload, or interfere with the app or its security;
  • resell, sublicense, or commercially exploit the service without our written permission;
  • upload anything harmful, unlawful, or that isn’t yours to share.

We can suspend or close accounts that break these rules.

6. The data you enter about other people

This is the part that matters most. PeriodBro is built around a hard truth: most of the data you put in is about someone else — a partner, a daughter, a mother. That data is intimate, and in today’s climate around reproductive information, it can be sensitive in ways that go beyond the personal.

So, plainly: only track someone with their knowledge and, where they’re an adult, their agreement. Tracking a partner’s cycle should be something she knows about and is okay with — ideally something you do together. For a minor child you’re responsible for, use your judgment as a parent and keep it age‑appropriate and respectful. You are responsible for having any consent or legal right needed to enter another person’s data, and for using it only to support them. Don’t use PeriodBro to monitor someone covertly or to control them. We provide the tool; how you treat the people in it is on you.

7. Subscriptions, trials, and payments

Some features are free; others need a paid subscription. If you start a free trial, we’ll tell you how long it lasts and what happens when it ends. Paid plans are billed in advance through whichever platform you signed up on (for example, an app store or our web payment processor), and unless you cancel they renew automatically for the same period at the then‑current price.

  • Cancelling: you can cancel anytime through your account or the app store you bought through; cancellation takes effect at the end of the current billing period and stops the next renewal.
  • Refunds: where you bought through an app store, refunds follow that store’s policy. Where you bought through us directly, reach us through our contact form. Nothing here removes any statutory refund or withdrawal rights you have under your local consumer law.
  • Price changes: if we change subscription prices, we’ll give you notice before it applies to a renewal, and you can cancel if you don’t want to continue.

8. Intellectual property

The app, the site, the PeriodBro name and logo, the articles, and the design are ours (or our licensors’) and stay ours. We give you a personal, limited, non‑exclusive, non‑transferable licence to use the service for its intended purpose while these Terms are in force. That licence doesn’t let you copy, modify, distribute, or build on our content beyond normal personal use.

The data you enter stays yours. By entering it you give us the limited permission needed to store and process it so the service can work — and only that. What we do and don’t do with it is set out in the Privacy Policy.

9. Third‑party services

PeriodBro runs on top of other people’s infrastructure — hosting, app stores, and payment processors among them. Your use of those is also governed by their terms, and we aren’t responsible for how they operate. If a third party changes or withdraws something we depend on, parts of the service may change with it.

10. Availability and changes to the service

PeriodBro is run by one founder and is still early. We’ll do our best to keep it working, but we can’t promise it will always be available, uninterrupted, or bug‑free, and we may add, change, or remove features over time. If we ever discontinue a paid feature you’ve already paid for, we’ll handle it fairly.

11. Medical disclaimer

PeriodBro provides general information and tracking, not medical advice. Nothing in the app or the articles is a diagnosis, a treatment recommendation, or professional medical guidance, and using it doesn’t create any clinician‑patient relationship. For anything concerning the health of the person you’re supporting — symptoms, contraception, fertility, pain, mood, or anything that worries either of you — talk to a qualified healthcare professional. In an emergency, contact local emergency services.

12. No warranties

The service is provided “as is” and “as available.” To the fullest extent the law allows, we disclaim implied warranties of merchantability, fitness for a particular purpose, and non‑infringement, and we don’t warrant that predictions or information will be accurate or complete. Some consumer laws give you guarantees that can’t be excluded; nothing here limits those.

13. Limitation of liability

To the fullest extent permitted by law, PeriodBro won’t be liable for indirect, incidental, special, or consequential losses, or for lost profits or data, arising from your use of the service. Where we are liable, our total liability is limited to the amount you paid us for the service in the twelve months before the claim. Nothing in these Terms limits liability that can’t be limited by law — including for death or personal injury caused by negligence, fraud, or your non‑excludable consumer rights.

14. Indemnity

If your misuse of the service, your breach of these Terms, or your handling of another person’s data without the right to do so leads to a claim against us, you agree to cover the reasonable costs and damages that result, to the extent the law allows.

15. Suspension and termination

You can stop using PeriodBro and delete your account at any time. We can suspend or close an account that breaks these Terms or puts other people or the service at risk. When an account ends, your right to use the service ends with it; the sections that by their nature should survive (such as intellectual property, disclaimers, liability, and indemnity) continue to apply. For what happens to your data on closure, see the Privacy Policy.

16. Changes to these Terms

We’ll update these Terms as the product and the law change. The “Last updated” date at the top always reflects the most recent version. For material changes that affect your rights, we’ll give notice by email (if we have one for you) or a prominent notice on the site before they take effect. Continuing to use the service after that means you accept the new Terms.

17. Governing law and disputes

These Terms are governed by the law of the country where PeriodBro’s operator is established, without affecting the mandatory consumer‑protection rights of the country you live in — those always apply to you. We’d much rather sort out any problem directly first, so please reach out through our contact form before anything formal. If you’re an EU consumer, you can also use the European Commission’s Online Dispute Resolution platform.
