Privacy policy

Privacy policy.

Personal data processing rules for the mrumi.com service.

Data controller

The data controller is Aleksandra Bogocz, who runs the mrumi.com project. Contact: hello@mrumi.com.

Scope of processed data

The Controller processes account data (email address and hashed password), data provided by the User while using the Service, technical data (IP address, anonymous application error logs), and data about how the Service is used.

Purposes and legal bases

Data is processed to provide the Service (Art. 6(1)(b) GDPR), to ensure security and prevent abuse (Art. 6(1)(f) GDPR), to analyse how the Service is used and to improve it (Art. 6(1)(f) GDPR, and for performance cookies Art. 6(1)(a) GDPR, consent), and — solely if the User signs up — to deliver the newsletter (Art. 6(1)(a) GDPR, consent).

Recipients of data

Data may be entrusted to processors acting on the Controller's behalf to the extent necessary to provide the Service. Some processors may be located outside the European Economic Area; in such cases transfers rely on standard contractual clauses approved by the European Commission. The Controller does not sell data and does not share it for advertising purposes.

Retention period

Account data is retained until the User deletes the account; after deletion — for the period necessary to establish, exercise, or defend legal claims (Art. 118 et seq. of the Polish Civil Code). Newsletter subscriber data — until consent is withdrawn. Application error logs, technical data, and analytics data — for the period necessary to fulfil the purpose for which they were collected.

User rights

The User has the right of access, rectification, erasure, restriction of processing, objection, data portability, and withdrawal of consent. To exercise any right, contact hello@mrumi.com. The Controller responds within one month (GDPR Art. 12(3)).

Right to lodge a complaint

Every data subject has the right to lodge a complaint with the supervisory authority — the President of the Polish Personal Data Protection Office (uodo.gov.pl).

Cookies and analytics

The Service uses strictly necessary cookies (authentication session, language, theme and panel settings) — Art. 399 of the Polish Act of 12 July 2024 on Electronic Communications Law. Without the User's consent, the Service counts visits without cookies: a one-day, irreversible hash is derived from the IP address and browser data, and the IP address itself is not stored (Art. 6(1)(f) GDPR). With consent to performance cookies, the Service remembers the browser, analyses how pages and tools are used and records visits with form fields hidden, to improve the Service (Art. 6(1)(a) GDPR). The providers of the analytics tools process data within the European Union; analytics data is not used for advertising and is not sold. Consent can be changed or withdrawn at any time in Cookie settings in the site footer or in the account settings. In the newsletter, the Administrator checks whether a message was opened and which links were clicked, using an invisible image in the email and link redirection by the email provider (Resend). This data helps assess which content is useful, is not used for profiling or advertising, and is processed under the newsletter consent (Art. 6(1)(a) GDPR) until it is withdrawn. Open tracking can be disabled by blocking images in your email client.

Security

Connections to the Service are encrypted (HTTPS). Passwords are stored in hashed form. Access to personal data is limited to authorized persons.

Changes to the policy

The Controller announces material changes to this policy with appropriate advance notice — by email (if the User has an account) or via an on-site notice.

Cattery directory

The Service maintains a public directory of cat catteries. That data does not come from the data subjects themselves but from publicly available cattery registers kept by feline organisations (including FPL, WCF, TICA) and from cattery websites (Art. 14 GDPR). The published fields are: cattery name together with its prefix, town and region, approximate location, breeds, website address, and club affiliation with a reference to the source. Email addresses and phone numbers obtained from public sources are not published.

The legal basis is the legitimate interest of the Controller in maintaining a directory of catteries operating under the supervision of feline organisations (Art. 6(1)(f) GDPR). The data is retained until an objection is raised or until the purpose for which it was collected ceases.

A person running a cattery has the right of access, rectification, erasure, and objection to the processing (Art. 21 GDPR). It is enough to state the cattery name and write to hello@mrumi.com or use the contact form — the entry then stops being published and the cattery name is added to an exclusion list that prevents it from being re-added at the next directory update. We respond within one month.
