Our commitment
How We Handle Reviews
CalcStack does not fabricate reviews, purchase testimonials, or incentivize positive feedback. Every review published on this page will be from a verified account holder who has embedded at least one tool on a live website.
We display all reviews, positive and negative, without editing. If a review identifies a product gap, we address it in the product, not by suppressing the review. This transparency is a deliberate choice: honest feedback from real users is more valuable than a curated wall of five-star quotes.
As the platform grows, reviews will also appear on third-party platforms where CalcStack cannot control the narrative. We welcome that accountability.
