Published methodologyEach score follows open rules, with a supplier right of reply.
Time-stamped consentEvery ticked box is tracked, dated and revocable in one click.

Frequently asked questions

What you're wondering

Do you sell my data?+

No, never. You send explicit requests to declared partners, only for the purposes you have ticked — revocable in one click.

Is it really free?+

The diagnosis and the first result are free, no e-mail. On recoveries, our partners are paid only on success.

How do you make money?+

On success on overcharges, through connections with declared partners, and through maintenance subscriptions. Everything is published.

Do you sell energy?+

Never. This neutrality is the condition of our independence — a poorly rated supplier can remain a partner, we write it in black and white.

Can I withdraw a consent?+

Yes, at any time and in one click from your client area. Each consent is time-stamped and kept as proof — never deleted, but revocable.
