Terms of use

Operator and scope

TADNA LTD (16394791) provides Tadna as an information and comparison service. These terms cover the catalogue, search, comparisons, knowledge articles, forms and offer links; retailer terms remain separate.

Information service

Tadna organises technical information and does not provide laboratory certification or professional, financial, medical or legal advice. Publication means that internal evidence and consistency rules were met, not that every quality is warranted.

Limited licence

You may browse and share links for lawful personal or professional purposes under a limited, revocable, non-exclusive and non-transferable licence. No ownership in content, software, taxonomy or database is transferred.

Prohibited conduct

• Do not attack authentication, security, infrastructure or the private administration area.
• Do not disrupt service, introduce malicious code, overload resources or evade technical controls.
• Do not scrape abusively or reconstruct a substantial part of the database.
• Do not misrepresent Tadna content, remove attribution, send spam or infringe third-party rights.

Technical and AI-assisted content

Pages may combine manufacturer, retailer, regulator, specialist and other public sources. Automated systems, including AI, assist fact extraction, variant reconciliation, normalisation and multilingual drafting. Important compatibility, safety, support and specification decisions must be verified with a primary source.

Comparisons and variants

A canonical page groups commercial variants and comparisons use normalised values. Missing data is not proof of a difference or an absent feature. Product identity may be corrected when stronger evidence emerges.

Retailers and affiliate offers

Offers may be ordered using market, availability, condition, currency and total known price. A commercial relationship may exist. Your contract is exclusively with the retailer and you must verify seller, final price, tax, shipping, warranty and returns.

User communications

You must have the right to send material submitted through the form. You retain ownership but allow Tadna Ltd to use it as needed to investigate, reply, correct the catalogue and handle claims. Do not send credentials or unnecessary sensitive information.

Availability and liability

Functions may be corrected, changed, restricted, suspended or withdrawn. To the extent permitted by law, Tadna Ltd is not liable for indirect or unforeseeable loss caused by relying solely on unverified content, temporary outage or third-party acts. Mandatory liabilities and consumer rights remain unaffected.

Law and contact

The laws and courts of England and Wales apply, subject to mandatory consumer law and forum rights. Questions may be sent to tadna@tadna.com. The displayed date identifies the current terms.
