Contact & imprint

Last reviewed: 21 August 2026. One address reaches us for everything: questions about the figures, corrections, licensing, privacy and access problems.

Contact

General questions, corrections, licensing and press: info@costely.com. Privacy requests and accessibility reports go to the same address. We aim to answer within five working days.

Who runs this site

Costely is run privately and answers by e-mail at info@costely.com. Legally significant notices should be sent to that address; if a further particular is required of us in your country, ask and we will supply it.

Hosting

The site runs on a commercial hosting provider, which operates the servers and their logs on our behalf. What that means for your data is set out in the privacy policy.

Corrections

If a figure here contradicts its source, that is a defect and we want to know. Send the page address, the figure, and what the publisher says instead. Confirmed errors are corrected and the correction is noted.

Consumer disputes

The European Online Dispute Resolution platform closed on 20 July 2025, so there is no link to it here. Consumers in the EU can find the national alternative dispute resolution bodies through the European Commission’s consumer redress pages. We do not take part in proceedings before a consumer arbitration body.

Data sources

Costely publishes no data of its own. Every figure belongs to the statistical office that produced it; the full attributions sit in the sources register on each comparison page and in the methodology. Licensing questions about the underlying series should go to the publisher, not to us.
