Effective date: 30 June 2026. Last updated: 30 June 2026.
Scope note (read first). This policy covers only the PeriodBro iOS app distributed on the Apple App Store. It does not cover the PeriodBro website (periodbro.com) or the separate web app at app.periodbro.com — those run on a different platform with a different data model and are governed by their own website privacy policy. If you use both, each policy applies to its own product.
PeriodBro helps you understand and support the women in your life — a partner, a daughter, a mother — through the menstrual cycle. The data inside this app is intimate, and the climate around reproductive data is hostile. We built the iOS app so that this data never has to leave your hands. This page explains, in plain English, exactly how that works.
If you only read one sentence: the PeriodBro iOS app stores your data on your own device and, if you choose, in your own private iCloud. We run no server for your data, we have no account system, and we collect nothing about you. There is nothing on our side to sell, share, or hand over.
1. Who we are
The PeriodBro iOS app is published by Devlet Butaev, an independent sole proprietor (Devlet Butaev PR, Serbia). For privacy questions, use our contact form. A real person reads every message.
2. The short version of our data model
- No account. No login. The app does not ask you to register. There is no username or password, and we do not store your email address.
- Your data lives on your device. Everything you enter — profiles, period dates, phases, notes, moods — is stored locally on your iPhone.
- Optional backup is your own iCloud. If you turn on iCloud backup, your data is stored in your personal iCloud account (Apple’s private CloudKit database), encrypted by Apple. We have no access to it. We cannot read it, and we cannot retrieve it for anyone.
- No PeriodBro server. We operate no server that holds your personal or cycle data.
3. What data we collect
None. Under Apple’s definition, “collecting” data means transmitting it off your device in a way that makes it available to us or a third party. The PeriodBro iOS app does not do this. Your data stays on your device and in your own iCloud, both outside our reach.
This is why our App Store privacy label reads “Data Not Collected.”
4. What the app stores on your device (and only there)
For the app to work, the following is stored locally (and in your private iCloud only if you enable backup):
- Profiles you create for the people you track — a label or first name, optional birth year.
- Cycle data — period start/end dates, predicted phase, notes, mood entries, and any custom fields you add.
- App settings — your preferences, notification choices, and backup toggle.
We never see any of it.
5. What we explicitly do NOT do
- We do not use analytics, tracking, advertising, or crash-reporting SDKs that send your data anywhere.
- We do not track you across other apps or websites. The app does not ask for App Tracking Transparency permission because there is nothing to track.
- We do not access your contacts, photos, microphone, camera, or precise location.
- We do not sell, rent, trade, or share your personal information. There is nothing to sell — we don’t have it.
6. Notifications
PeriodBro uses local notifications only. Reminders are scheduled on your device based on your own data. No notification content is sent through our servers, because there are none.
7. Subscriptions and payments
PeriodBro offers an optional paid subscription, processed entirely by Apple through the App Store (StoreKit).
- We never see or store your payment card, billing address, or Apple ID password.
- Apple shares with us only the anonymous, aggregate information needed to confirm subscription status (for example, whether an active subscription exists) — never your identity.
- Your Apple ID is used by the operating system for purchases and iCloud. We do not store it.
Apple’s handling of your purchase is governed by Apple’s own privacy policy.
8. Your control over your data
Because everything is in your hands, you exercise your rights directly inside the app — no request to us required:
- Export data — produce a copy of your data from Settings.
- Delete all data — permanently erase everything from your device (and, if backup is on, from your iCloud) with a double confirmation.
- Turn backup on or off at any time in Settings.
Uninstalling the app removes local data. If iCloud backup was on, you can also delete the PeriodBro data from your iCloud storage in iOS Settings.
9. Your rights under GDPR and CCPA / CPRA
The PeriodBro iOS app processes your data locally, under your sole control, and we act as neither a controller nor a processor of any personal data held on our side, because we hold none. We have no copy of your data to access, correct, port, or erase — you do that yourself with the tools in Section 8.
If you believe we hold personal data about you (for example, because you also contacted us through the website), you can exercise your GDPR or CCPA/CPRA rights for that separate website data via our contact form, and the website privacy policy governs it.
10. Children
The PeriodBro iOS app is not directed at children. It is a tool for an adult who is caring for someone — including a parent supporting a daughter. If you use PeriodBro to track a minor in your care, you are responsible for ensuring this is lawful and appropriate in your jurisdiction. The data still belongs, ethically, to her, and we encourage you to be transparent with the people you track.
11. Reproductive data and legal requests
We want to be direct about this, because it is the reason the app is built the way it is: we cannot be compelled to hand over what we never have. Your cycle, fertility, and pregnancy-related data are not on any PeriodBro server. There is no database for a subpoena, court order, employer, insurer, or government agency to reach. Reproductive data belongs to the person it describes — not to us, and not to the state.
12. Security
Your data is protected by your device’s own security (passcode, Face ID / Touch ID) and, for backups, by Apple’s iCloud encryption. We do not introduce a server that could be breached, because we don’t operate one for your data.
13. Changes to this policy
We will update this policy if the app’s data handling changes. The “Last updated” date above always reflects the current version. Material changes will be noted in the app or on this page.
