About Caliper Press
Caliper Press records what online services cost today, what they cost at renewal, and how those payments add up over several years. We read published prices and terms every day, keep every reading with its date and source, and show the arithmetic behind each total. The aim is a plain answer, with evidence, to a practical question: what will this cost me now, and what will it cost later?
Alongside prices, we run a small set of technical checks: which AI crawlers websites allow in their robots.txt files, and whether a website negotiates hybrid post-quantum key exchange.
Who is responsible
Caliper Press is published by InbiTech OÜ, a company registered in Estonia, which answers for everything on this site: the numbers, the calculations, the wording and any errors. No provider we cover owns or funds the site, sees our results before publication or pays to be listed, checked or ranked.
- Contact: corrections@caliperpress.com, for errors and for any question about the data.
- Corrections: we reply within 48 hours and fix a confirmed error within 7 days; every fix is listed in the corrections log.
- How a number gets here: each price is read from the provider's own public page on a stated date and linked to that page; totals show their arithmetic; the methodology lists what we do not measure.
- Money: no affiliate links, ads or paid placements; the publisher pays for every check.
How the site works
one reading a day, each dated and linked
We read each provider's public page once a day and keep every reading with its date and source. Totals and comparisons are calculated from those readings, and every number on a page matches its data file.
We do not buy the products, log in to accounts, or test quality, speed or support. The methodology explains each step and its limits.
How we make money
no commercial links at launch
Commercial links: none at launch.
Caliper Press has no affiliate links, ads or sponsored placements, and no provider pays to be listed, checked or ranked. The publisher pays for all checks. If we join affiliate programs later, each paid link will be labeled where it appears, and this section will name the programs. Commission will not decide which plans we track, the numbers we publish or the order of any table.
Reporting an error
email us the page address
If a number on this site is wrong, email corrections@caliperpress.com with the page address and, if you have one, a public source. The corrections page explains how a report is checked and lists every correction; earlier readings are not silently overwritten.

Limits
a selected set; history since 27 September 2026
