Privacy Notice

Last updated: 24 September 2026

Who is responsible

The Maruva website at maruva.app and the Maruva mobile application (together, the Service) are run by the operator of the Service, who is the controller of your personal data. Contact:

This notice applies under the Law of Ukraine "On Personal Data Protection" and, where you use the Service from the European Economic Area or the United Kingdom, the GDPR and UK GDPR. It forms part of our Terms and Conditions.

The website

This website sets no cookies, runs no analytics and embeds no trackers. Our network provider, Cloudflare, processes connection data (IP address, requested page, browser type) to deliver the pages and protect them from abuse. We do not store that data ourselves.

What the application collects

Why we use it

We do not sell personal data, and we do not use it for third-party advertising.

Who processes it for us

The following providers process data on our behalf under their own data-processing terms. Several of them are outside Ukraine; transfers rely on their standard contractual safeguards.

Google

Apple

OpenAI

When you tap through to buy a product, you leave the Service for the merchant's own website. We do not send merchants your personal data; their privacy terms apply from that point.

How long we keep it

Your rights

You can ask us to access, correct, export or delete your personal data, to restrict or object to its processing, and to withdraw consent. You can edit your profile, preferences and diary in the application. Account deletion and data export are done by us on request: write to dev@maruva.app from the email address on your account and we will complete it within 30 days, confirming when it is done.

If you believe we have handled your data unlawfully, you may complain to the Ukrainian Parliament Commissioner for Human Rights or, in the EEA or UK, to your local supervisory authority.

Children

The Service is not directed at children. You must be at least 16, or the age of digital consent in your country if higher, to create an account. If you believe a child has given us personal data, contact us and we will delete it.

Security

Data travels over TLS and is stored on access-controlled servers with encrypted backups. No system is perfectly secure; if a breach affects your data we will notify you and the authorities as the law requires.

Changes to this notice

We will post any change here and update the date above. A material change will also be announced in the application before it takes effect.
