Photo reviews

Photos and experiences shared by contributors. Read below how we check submissions.

How reviews and confirmations work

We ask contributors to share a photo they took and their own experience. Reviews go through automated checks. Flagged reviews can be assessed manually. Approval is not a guarantee that a photo is unedited or free of AI generation.

  • Email address confirmed means the link sent to that address was used. It does not prove a purchase or the identity of a person.
  • Company management confirmed relates to access to this company page. A paid plan does not verify individual reviews.
  • A review invitation does not independently prove a purchase. An order reference supplied by a company is not independent purchase verification either.
  • Publishing a photo with a review does not automatically permit reuse in marketing. A subscription does not grant that permission either.

Kalkulator.cz targets everyday Czech consumers who want to reduce their monthly expenses without spending time researching dozens of providers themselves. The platform operates in the middle ground between a simple price aggregator and a personal savings assistant, offering features such as contract end-date monitoring and proactive alerts when a better deal becomes available. Its business model is funded by partner commissions rather than user fees, which means the comparison and advisory services carry no direct cost to the consumer. The platform covers a broad range of categories including electricity, gas, car insurance, property insurance, mobile tariffs, loans, and holiday bookings.
