Privacy policy

Version 2026-11-05 Español · English

Katai processes your data to provide your account, your subscription and the training analysis. You can contact the data controller at support@kat-ai.com.

Data we process

We process account and profile data, country and date of birth, the status of the subscription bought on the App Store or Google Play, consents, training activity, videos sent for analysis, technical results, security logs and support communications (including any screenshot you attach). The app also sends us technical data about your device and the app itself: device model and operating system version, app and update version, language, time zone, whether you have granted camera, microphone and notification permissions, and the free storage on your phone. We do not collect your location, the list of installed apps or advertising identifiers. For family seats we also process the link between the guardian account that pays for them and the accounts that use them. Payment is charged by Apple (App Store) or Google (Google Play) through your account with that store, under their own privacy terms; Katai does not receive or store your card details. RevenueCat, the provider we use to manage subscriptions, receives the status of your purchases from the store together with an internal identifier for your account, without your name or email.

Purpose and legal basis

We use the data to perform the contract, authenticate you, process payments, analyse sessions, prevent fraud, keep the service secure, diagnose and fix app issues (using the technical device data) and meet legal obligations. Optional messages are based on consent where applicable.

Retention and recipients

We keep the data while the account is active and for the applicable legal periods. When you delete your account we delete your videos and anonymise operational data, except for records that must be kept for tax obligations, fraud prevention or the defence of claims. Deleting your account does not cancel your store subscription: cancel it on the App Store or Google Play so that it does not renew. Providers such as Apple, Google, RevenueCat, Resend, hosting and monitoring act to provide the service under their own data protection terms.

Emails and notices

We send you service notices by email and as notifications in the app: welcome, end of the free trial, failed payments, cancellation (with an optional survey about the reason), renewal of annual subscriptions and, for the guardian of a family subscription, a weekly summary of the activity on their seats (which they can stop receiving with the link it includes). Only if you agree (when signing up, in the app Settings or in your web account) and you are 14 or older, we also send you news and tips: reminders to train again, your first correction, streaks and new belts. You can withdraw this at any time from those same places or with the unsubscribe link in each email.

To know whether our emails arrive and are useful, our provider Resend records whether they are delivered, whether they bounce, whether they are opened (with a tracking image) and whether a link is clicked. We only use this data in aggregate and to stop writing to addresses that do not work.

Minors and accounts managed by a guardian

Children under 14 can only use Katai’s paid features with a seat paid for by their parent or legal guardian (the guardian). When buying seats, the guardian declares that they are an adult and, for minors, their legal representative, and authorises the processing of their data to provide them with the service. That declaration, together with the purchase made with their App Store or Google Play account, is the consent required by law for children under 14 (Article 8 of the GDPR and Article 7 of the Spanish data protection act, LOPDGDD). We keep the date, the version of these texts and the IP address from which it was given.

From their web account, for each seat the guardian sees the nickname, avatar and email of the account using it, since when, the date of the last training, which days it trained in the last week, its streak of consecutive days, its level, its belt and the devices where the app is open (and can close those sessions). They do not see that account’s videos, scores or messages. The guardian can pause the account (it cannot be used until they reactivate it), free the seat (the account is kept, without paid access) or delete it (its data is deleted as with any account deletion). Whoever uses a seat can ask for deletion from the app: we pass the request on to the guardian by email.

Accounts of users under 18 cannot enable the public profile or upload their own photo (they can only choose one of Katai’s avatars), and their nicknames are moderated. A minor can sign up with an email address belonging to the guardian (for example, an alias such as name+child@…): in that case, the sign-in codes go to the guardian.

From the age of 14, minors exercise their rights themselves; below that age, their guardian exercises them by writing to support@kat-ai.com or from their web account.

Cookies and website measurement

When you visit kat-ai.com we ask you about two uses of cookies, which you can accept or reject separately. Rejecting them does not stop you from using the website.

Our own measurement. We count visits to know how people find us and which campaigns work. If you accept it, we store the first-party cookie katai_vid (a random identifier) and remember in your browser for 30 days the campaign you came from. If you do not, we count the visit without cookies, with an anonymous identifier that changes every day and cannot recognise you. Only Katai uses this data, and we do not store your IP address with the visit.

Advertising. Only if you accept it, the kat-ai.com home page loads the tags of Meta (Facebook and Instagram), Google (Google Tag Manager and the Google tools managed with it, such as Google Ads and Google Analytics) and TikTok. These companies receive the pages you visit, your IP address, data about your browser and device, and whether you tap the app download buttons. They use it to measure which Katai ads work and to show you Katai ads on their platforms, and may link it to your account with them under their own policies. The other pages (these legal texts, help, the web account and public profiles) do not load these tags, and neither does the app.

For collecting and sending that data, Katai is a joint controller with each of these companies, which decide as controllers what they do afterwards: Meta Platforms Ireland Ltd. (its privacy policy), Google Ireland Ltd. (its policy) and TikTok Technology Limited (its policy). They may process the data outside the European Economic Area, for example in the United States, under the EU-US Data Privacy Framework or the European Commission's standard contractual clauses.

The legal basis for both uses is your consent (Article 6(1)(a) GDPR and Article 22.2 of the Spanish LSSI). You can withdraw or change it at any time with the button below; if you withdraw consent to advertising, we delete these companies' cookies from our domain.

Google's cookies depend on the tools enabled in Google Tag Manager, which sets no cookies itself.

Your rights

You can request access, rectification, erasure, restriction, objection and portability, and withdraw a consent, by writing to support@kat-ai.com. From your account at kat-ai.com/cuenta.html you can also correct your data, download it (a file with your account, your corrections and your activity) and delete the account. You can also lodge a complaint with the competent data protection authority.

Security and changes

We apply technical and organisational measures to limit access and detect abuse. We will publish new versions here and ask for your acceptance again when a change is material.
