Rouge
Privacy Policy
Rouge is built on one idea: your body's data is yours, and yours alone. This policy explains what that means in practice.
Last updated 22 October 2026. Rouge is made by Lische Dynamics Limited, a company registered in Kenya.
The short version
- Your cycle data never leaves your device. Your period dates, symptoms, moods and notes are stored only on your phone, and we never receive them.
- There is no account and no login. We do not ask for your name, email or phone number to use the app.
- We never sell your data, and we never show you ads.
Your cycle data stays on your device
Everything you log in Rouge, including your period dates, symptoms, moods, flow and any notes, is stored in an encrypted database on your phone. It is private by design rather than by policy, because we simply never receive it. There is no Lische Dynamics server holding your health information, so there is nothing for us to lose, sell or hand over.
Because this data lives only on your device, it is your responsibility to keep too. If you delete the app or reset your phone without a backup, your logged history goes with it. You can erase everything at any time from within the app under Settings, using Delete all data, which removes it permanently from your device.
Apple Health and Health Connect
If you choose to, Rouge can read period history you already keep in Apple Health on iPhone, or in Health Connect on Android, so you do not have to enter your history twice. On Android, Rouge asks to read your menstruation records and, if you allow it, records older than 30 days, so your full history comes across. This happens only after you grant permission on your device, the data is used only inside the app on your phone, and it is never sent to us. Rouge only reads this information: it never writes to Apple Health or Health Connect.
You can turn this off at any time, in the Health app's settings on iPhone or in Health Connect's settings on Android, and Rouge works fully without it.
Rouge's use of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements.
Anonymous product analytics
To understand how the app is used and where it can be improved, Rouge collects a small amount of anonymous product analytics. These are limited to a fixed set of app events, for example that the app was opened, that a screen was viewed, or that a purchase completed. Apart from those events, the app sends only the crash reports described below.
Your cycle data is never part of this. Period dates, symptoms, moods and notes are never sent through analytics. The analytics do not identify you personally and are not linked to a name, email or phone number.
This analytics data is processed on our behalf by a third-party analytics provider, on servers in the European Union, and is held there for up to seven years under our agreement with that provider. You can turn analytics off at any time in Settings, and doing so stops any further events from being sent.
Crash reports
If Rouge crashes or runs into an unexpected error, it sends a crash report so we can find and fix the problem. A crash report contains the type of error and its message, where in the app's code it happened, the screen you were on, your device model, and your operating system and app versions.
Crash reports are designed to exclude your cycle data and your name. Before an error message leaves your phone, the app removes dates, email addresses, long numbers and the first name you gave the app. Errors raised by your phone's operating system carry technical details about the app's code, not what you logged. Crash reports are not linked to a name, email or phone number.
Crash reports are processed by the same analytics provider, on servers in the European Union, and held for up to seven years. Turning analytics off in Settings also stops crash reports.
Purchases
Rouge offers optional paid features, including detailed cycle reports and a subscription. These purchases are handled entirely by Apple through the App Store on iPhone, and by Google through Google Play on Android. We receive confirmation from the store that a purchase was made so we can unlock the feature, but we never see or store your card number or payment details. Apple's and Google's own privacy policies govern how your payment information is handled.
If you ask Apple for a refund, Apple may ask us for information about that purchase before it decides. Where that happens, we tell Apple how much of the purchase you had used, whether the app delivered it properly, whether we had offered you a free trial or sample beforehand, and what we think the outcome should be. Apple makes the decision, not us.
If you bought through Google Play, refunds are handled by Google under Google Play's own policies, and we do not send Google any information about how you used the purchase.
We never send your cycle data as part of this. Your period dates, symptoms, moods and notes are never included in a refund request, and there is nothing in what we share that describes your health.
By buying something in Rouge you agree to us sharing that purchase information with Apple when it asks, as set out in our Terms of Use. If you have questions about this, or you want to withdraw that agreement, email legal@lischedynamics.com.
Ideas board
Rouge has an Ideas board where you can suggest features and vote for the ideas you would like us to build next. Using it is optional, and nothing you log in Rouge is ever sent with an idea or a vote.
When you send an idea, we receive the words you wrote and a few details about the app: whether it runs on iPhone or Android, whether you are on a free, trial or paid plan, the app's language and version, and, while the Show my country flag switch is on, the country from your phone's region setting. That is a setting on your phone, never your location. When you vote, we receive which idea you voted for and the same details.
To count each vote once and to limit how many ideas and votes can be sent in a day, the app creates a random code the first time you open the board and keeps it on your phone. The code is not linked to your name, email or phone number. Your ideas and votes are stored with a scrambled form of it, which cannot be turned back into the code. Delete all data in Settings also deletes the code. Our server also sees your device's internet address when the app connects. We use it only to limit how often the board can be called, and we do not store it with your ideas or votes.
We read every idea before it appears on the board. Approved ideas are public: everyone who uses Rouge can see them, translated into their own language, together with the number of votes and the flags of the countries those votes came from. Please leave personal and health details out of your ideas. Ideas and votes are stored and translated by service providers we use to run the board, whose servers may be outside your country.
We keep ideas and votes for as long as the Ideas board runs. To have an idea you sent removed, email rouge@lischedynamics.com with its text. You can report any idea on the board by pressing and holding it.
Children
Rouge is a health app that may be used by people under 18. Apart from the anonymous product analytics described above, and any ideas or votes you choose to send from the Ideas board, we receive no personal information from anyone who uses the app, regardless of age: there is no account, and cycle data stays on the device. (Our website's gift and Android waitlist pages work differently: see below.) Rouge's age rating is shown on its App Store and Google Play listings.
Website and waitlist data
This section is about our website, not the app. Two things here work differently from the rest of this policy: we count visits to our web pages, and until Rouge reached Android, the gift page at lischedynamics.com/gift asked for an email address on an Android waitlist form.
We count visits to our web pages so we can see which pages people find useful and whether they go on to the App Store or Google Play. This counting is anonymous and deliberately small. We record the address of the page, the site or search engine you arrived from, general details about your browser and device, and your IP address, which is used to work out an approximate country. We do not set cookies, we do not store anything in your browser, and we do not collect your name, your email address or any account. Each page view is counted on its own, so it is not joined up with your other visits, with anything you do in the Rouge app, or with any waitlist email address you may have given us. This counting is processed on our behalf by the same third-party analytics provider used by the app, on servers in the European Union, and is held there for up to seven years.
If you would rather not be counted, turn on Do Not Track or Global Privacy Control in your browser. Our website checks both and sends nothing at all when either is on. Blocking JavaScript for this site has the same effect.
If you gave us your email address on the Android waitlist form, Lische Dynamics Limited is the controller of that data. We store the email address you gave us, the time you submitted it, and the fact that it came from the Android waitlist form. We use it to tell you that Rouge is on Android, and occasionally to share news about our apps. We do not use it for anything else, and we never sell it or pass it to anyone for their own marketing.
You can unsubscribe or ask us to delete this information at any time by emailing legal@lischedynamics.com. We keep it until you unsubscribe or ask us to remove it.
Your rights
Because your cycle data never leaves your device, you are always in direct control of it: you can view it, change it or erase it entirely from within the app at any time. For the anonymous analytics we hold, you can stop collection at any time in Settings, and you may contact us to ask about the data we process. Depending on where you live, you may have additional rights under laws such as the Kenya Data Protection Act or the EU General Data Protection Regulation, and we will honour those rights. If you gave us your email address on the Android waitlist, your rights over that are set out in Website and waitlist data above.
Changes to this policy
If we change how Rouge handles data, we will update this page and change the date at the top. Significant changes will also be noted in the app.
