About Pevlika

What Pevlika is

Pevlika brings together 582 apps: file and image tools, 138 calculators, developer and writing utilities, device tests and 105 games. Everyday apps need no account and no installation, and they are built to work on phones as well as computers.

How calculators work

Each calculator explains its inputs and shows the formula it uses. Health and finance calculators add a “How it’s calculated” section with the method and its published sources, such as the Mifflin–St Jeor equation for calorie needs or the standard annuity formula for loans. Results are estimates for planning and learning; they are not medical, legal or financial advice.

How apps are checked

Every release passes automated tests before it reaches the site: rule and calculation tests for each app, and browser tests that use the apps at phone and desktop sizes, in light and dark themes, under the site’s strict security policy. A release that fails any check is not published.

Privacy first

Most apps run entirely in your browser, so what you type or open stays on your device. Apps that need a server process your file only to produce the result and delete it automatically. The privacy page lists exactly which apps use the server or other websites.

Advertising

Some tool pages show clearly labelled ads after the app, never inside it or next to its controls. Games may show an ad at a natural break, such as the pause menu or before the next level, and play continues if no ad is ready. Account-backed creation pages are ad-free.
