Terms of Service
Version 4 · published 9 Nov 2026
Effective from 09 November 2026.
§ 1. General provisions
These Terms set out the rules for using the Kosvia website (the “Service”) and are the terms of electronically supplied services within the meaning of the Polish Act of 18 July 2002 on Providing Services by Electronic Means.
The Service is provided by Mateusz Wyka Vetch, Jaszczów 11A, 21-020 Milejów, Poland, tax ID (NIP) 5050134076 (the “Provider”). Contact: e-mail kontakt@kosvia.pl, phone +48 724 050 102.
The Service is currently a demonstration version. All services are free of charge. Prices and shops shown in the Service are examples and are not an offer to sell.
In these Terms: User means a person using the Service; Account means a User’s individual account; User Content means reviews and other content a User posts in the Service; Consumer means a User who is a consumer within the meaning of Article 22¹ of the Polish Civil Code.
§ 2. Services
The Provider offers the following services free of charge, all available in the Service on the date these Terms take effect:
without an Account: browsing the catalogue of cosmetic products and the ingredient library, product search, comparison and the dupe finder;
with an Account: a beauty profile, a product fit score (Personal Match), a product shelf, price alerts (shown in the Service when a price drops to your threshold — no e-mail notifications), a skin diary and a routine planner;
Kosvia AI — an AI shopping assistant that answers questions about products in the Service’s catalogue;
posting reviews of the Service.
Some features are marked Premium. Until payments are launched, the Premium plan is not sold and the Provider may make it available to selected Users free of charge. Before payments are launched, these Terms will be amended to set out the price, billing period, renewal, cancellation, right of withdrawal and complaints for paid services.
The Provider is not the manufacturer, distributor or seller of the cosmetics shown and does not sell them in the Service. Links to shops, where present, lead to websites of independent businesses. If the Provider starts using affiliate links for which it may receive a commission, they will be clearly marked.
§ 3. Technical requirements and security
Using the Service requires a device with internet access and an up-to-date browser with JavaScript and cookies enabled.
The Service stores in the browser only the cookies and data it needs to work, such as keeping you signed in and your chosen language. It uses no analytics or advertising cookies. They are listed, with their purpose and how long they are kept, in the Privacy Policy (section 11).
Using services online carries common risks such as malware, phishing or a stolen password. The Service uses an encrypted connection (HTTPS) and stores passwords only as hashes. Users should keep their password safe and not share it.
§ 4. Account
An Account may be created by a person aged 16 or over. When registering, the User gives an e-mail address, a password and a date of birth — the latter only confirms the User’s age and is not stored. After registration the Provider sends a link confirming the e-mail address; the Account works before it is used as well.
The agreement for an Account is concluded for an indefinite period when the Account is created and these Terms are accepted.
The User may terminate the agreement at any time by deleting the Account in their profile. The Account is deleted 7 days after the request. Until then the User can withdraw the request with the link in the e-mail or by signing in and choosing “Keep my account” in their profile. Signing in alone does not cancel the deletion.
A Consumer may also withdraw from the Account agreement within 14 days of concluding it, without giving reasons and at no cost — by deleting the Account or sending a statement to kontakt@kosvia.pl.
§ 5. Rules of use and response to breaches
The User undertakes to:
use the Service in accordance with the law, these Terms and good practice;
not post illegal content;
provide truthful information when registering;
not disrupt the Service, including by attempting unauthorised access or by bulk-downloading data with automated tools.
If these Terms are breached, the Provider may — in proportion to the seriousness of the breach — hide or remove User Content, temporarily suspend access to the Account or terminate the agreement with 14 days’ notice. Immediate termination is possible only for a serious or persistent breach, e.g. posting illegal content again after earlier removal or attempting to compromise the Service’s security.
Independently of the above, the Provider may take immediate protective measures, e.g. sign out all sessions of an Account after detecting the use of a stolen sign-in token.
The Provider informs the User of the measure taken and the reason for it, unless the law or security considerations do not allow it. The User may appeal against such a decision under § 8.
The Provider may also terminate the agreement with 14 days’ notice if the Service is closed.
§ 6. Reviews and reporting content
Only signed-in Users can review the Service — one review per Account. A review is published immediately, without prior moderation, with the first name given in the Account, if any. The Provider does not otherwise verify whether the author has used the Service.
Reviews may be positive or negative. The Provider does not remove or hide reviews solely because they are unfavourable and does not publish reviews in exchange for benefits.
The User grants the Provider a free, non-exclusive licence to display their review in the Service for as long as it is published. The User may delete the review at any time.
Reviews are moderated by a human — the Provider, without automated tools — after a report or on the Provider’s own initiative. The Provider may hide or remove a review that breaches the law or these Terms, in particular one that is offensive, promotional, contains other people’s personal data or is not about the Service. The author is informed of the decision with the reasons for it and may appeal under § 8.
Anyone can report content they consider illegal by writing to kontakt@kosvia.pl. A report should explain why the content is illegal, identify it precisely (e.g. the page address), give the reporter’s name and e-mail address — except for reports concerning the offences referred to in Article 16(2)(c) of the Digital Services Act — and include a statement that it is made in good faith. The Provider confirms receipt, handles the report without undue delay, objectively and diligently, and informs the reporter of its decision.
The single point of contact for Users, Member State authorities and the European Commission under Articles 11 and 12 of Regulation (EU) 2022/2065 (Digital Services Act) is kontakt@kosvia.pl. Communication is in Polish or English.
§ 7. Nature of the information
The Service provides information about cosmetic products and their ingredients. It is not a medical service — it does not diagnose or treat skin conditions and does not replace a consultation with a doctor or dermatologist.
The Personal Match score is calculated automatically by an algorithm from the product’s ingredients and the User’s profile. It is a cosmetic recommendation, not a guarantee that a product will be well tolerated.
Product data (names, brands, categories, ingredient lists, photos) comes mainly from Open Beauty Facts. The Provider does not test formulas in a laboratory — check the ingredients on the packaging before buying, especially if you have allergies.
Ingredient information (INCI names, functions, entries in the annexes to Regulation (EC) No 1223/2009) comes from the European Commission’s CosIng database. CosIng is for information only: an ingredient appearing in it does not mean it is permitted for every use or that a product containing it is safe for a particular person.
The Provider makes every effort to keep the information accurate and up to date and corrects errors it learns about — please report them to the address in § 1. Kosvia AI answers are generated automatically and may contain errors.
§ 8. Reports, complaints and appeals
Technical problems, complaints and appeals against moderation decisions can be sent by e-mail to kontakt@kosvia.pl or by post to the Provider’s address.
A message should include contact details and a description of the problem and, if possible, when it occurred.
The Provider handles it within 14 days of receipt and replies to the address it was sent from.
Where the rules on the supply of digital services apply to the agreement with a Consumer, the Consumer has the rights for non-conformity of the service with the contract under the Polish Consumer Rights Act, in particular to have the service brought into conformity. These Terms do not limit those rights.
§ 9. Liability
The Provider makes every effort to keep the Service available and working correctly. In the demonstration version, however, there may be technical breaks, errors and changes to features.
These Terms do not exclude or limit the Provider’s liability towards Consumers to the extent the law does not allow it.
§ 10. Personal data
How personal data is processed is described in the Privacy Policy.
§ 11. Out-of-court dispute resolution
Consumers may use out-of-court complaint and redress procedures, for example by asking a municipal or district consumer ombudsman or the regional Trade Inspection office for help. More information: uokik.gov.pl.
§ 12. Changes and final provisions
The Provider may amend these Terms for good reason: changes in the law, changes in the scope of services (including launching payments, adding or withdrawing features) or for security reasons.
Users with an Account will be notified of material changes by e-mail at least 14 days before they take effect, together with the amended Terms. A User who does not accept the changes may terminate the agreement with immediate effect before that date by deleting their Account. On request, the Provider will send the text of any earlier version of these Terms.
Polish law applies to matters not covered by these Terms. This choice of law does not deprive Consumers of the protection of provisions that cannot be excluded by agreement.
These Terms are available free of charge in the Service in a form that allows them to be downloaded, stored and printed. In case of discrepancies, the Polish version prevails.
