Privacy Policy

Who we are

This policy covers the website krumay.app and the Kru May mobile app for iPhone, iPad and Android. Both are published by Anzar Technologies LLC, the data controller. You can reach us at contact@anzarsystems.com.

Kru May does not ask you to create an account, and we do not ask for your name or email address in order to use the app.

On the website

We use the following data when you visit krumay.app:

• Hosting (Vercel). Our host processes technical data such as your IP address, browser and the pages requested, in order to serve and protect the site.
• Audience measurement without cookies (PostHog). We measure page views, clicks on the store buttons, language changes, articles read and page performance. This tool stores nothing on your device, and your IP address may be used to work out an approximate location.
• Google Analytics, only if you accept. Nothing from Google loads until you accept the cookie banner. If you accept, Google receives the pages you visit, information about your device and browser, and an approximate location. Advertising features are turned off.

Links to the App Store, Google Play and Instagram take you to services that apply their own privacy policies.

Cookies on the website

The only cookies are those of Google Analytics, _ga and _ga_QNBPP33CN5. They are set only after you accept and last up to two years.

Your choice is kept in your browser for six months, under the name krumay_consent. To change it at any time, use Manage cookies at the bottom of each page. If you withdraw your consent, Google Analytics stops and its cookies are deleted.

In the app

Stored on your device. Your progress, favorites, flashcards, preferences and reminders stay on your device. You can erase them from the Profile tab or by uninstalling the app.

Anonymous identifier. The app creates a random identifier for your installation. It lets the services below recognize the installation without knowing who you are. It remains on the device after you erase your data so that a subscription stays linked; uninstalling the app removes it from the device.

Other data used by the app:

• Usage statistics (PostHog). Events such as stories opened, onboarding steps and subscription screens, with device information. Your IP address may be used to work out an approximate location. Session recording is turned off.
• Subscriptions (RevenueCat, Apple, Google). Apple or Google handle your payment, and we never see your card details. RevenueCat receives your anonymous identifier and your purchase and subscription status so that your access can be unlocked.
• Illustrations and audio. When you open a story, these files are downloaded from a content delivery network, which processes your IP address to send them.
• Recordings for pronunciation exercises. The microphone is used only if you start an exercise and allow it. Recordings stay on your device. They can be transcribed by the speech recognition of your device, on the device when possible; on iPhone and iPad, Apple may otherwise process them. We never receive them.
• Reminders. Notifications are scheduled on your device and only if you turn them on.

Measuring our advertising (iPhone and iPad)

To find out which of our ads lead to installs and subscriptions, the iOS app uses AppsFlyer. It receives your anonymous identifier, device data such as the vendor identifier (IDFV), your IP address, and install, trial and subscription events, including revenue from subscriptions, which RevenueCat sends to it.

AppsFlyer passes these results on to the advertising platforms we use, such as Meta and TikTok, so that campaigns can be measured and optimized. The Android app does not use AppsFlyer.

iOS asks whether you allow tracking. If you allow it, the advertising identifier (IDFA) is also shared with AppsFlyer and RevenueCat. If you decline, the IDFA is not shared: measurement continues without it, using the data above and statistical methods, and every feature of the app works the same. You can change your answer in the iOS settings.

Why we use this data

• To provide what you ask for (the site, the app, your subscription): performance of our contract with you.
• To keep services secure and understand how they are used (hosting, statistics without cookies, app statistics, measuring our advertising): our legitimate interest in running and improving Kru May and funding it. You can object to this at any time.
• Google Analytics cookies and the advertising identifier: your consent, which you can withdraw at any time.
• To meet legal obligations, for example accounting for subscriptions.

Recipients and transfers

We do not sell your data for money. It is shared only with the providers named in this policy and, where required, with the authorities. Some providers, including those based in the United States, process data outside your country. Where the law requires it, these transfers rely on safeguards such as the European Commission’s standard contractual clauses.

How long we keep data

• On your device: until you erase it or uninstall the app.
• Google Analytics: event data for 2 months, user-level data for 14 months, cookies for up to two years.
• Consent choice: six months.
• Statistics, advertising measurement and hosting logs: for as long as needed for these purposes, according to the settings of each provider.
• Subscription records: for as long as needed to provide your access and meet our legal obligations.

Your rights

Depending on where you live, you may have the right to access, correct or delete your data, to restrict or object to its use, to receive it in a portable format and to withdraw your consent. To exercise these rights, write to contact@anzarsystems.com. Since Kru May has no accounts, we may ask for your anonymous identifier or purchase details to find your data.

You can also complain to the data protection authority of your country.

Children

Kru May is not intended for children under 13, or under the minimum age set in their country. We do not knowingly collect their data. If you think we have, please contact us so that we can delete it.

Changes to this policy

We may update this policy when our practices or the law change. The date at the top of this page shows the latest version. If a change is significant, we will also let you know on the site or in the app.
