Frequently Asked Questions
What is AnyServ?
AnyServ is a free, ever-growing library of online tools covering finance, business, health, sport, gaming, technology and everyday life. Every tool runs instantly in your browser - no registration, no downloads, no paywalls. We add new tools regularly as the catalog grows.
What categories of tools does AnyServ offer?
AnyServ covers: Finance & Banking (VAT, mortgage, APR, salary, investments), Tax & Accounting, Currency & Crypto, Business & HR, Health & Fitness (BMI, calorie calculator), Sport & Training, Gaming utilities, Tech & Hosting, and general everyday calculators. The catalog grows continuously.
Are my data safe? Does AnyServ store what I enter?
Yes, completely safe. Every calculation runs locally inside your browser. Nothing you type is ever sent to our servers - we literally cannot see it. AnyServ stores no personal data, no calculation history, and no usage profiles.
How accurate are the results?
Our calculators are built on official rates and formulas from central banks (ECB, Fed, BoE), national tax authorities (EUR-Lex, HMRC, IRS) and international standards bodies. Rates are reviewed monthly. Results are indicative - always consult a certified professional before making financial or medical decisions.
Why is AnyServ free – and will it stay that way?
We believe essential tools should be accessible to everyone – freelancers, students, small businesses and individuals alike. AnyServ is sustained by non-intrusive display advertising and carefully selected affiliate partnerships. We never sell user data because we don't collect any. 90% of everything you see here will always be €0, no registration, no catch. We are working on one upcoming feature that will be a significant leap in how fast you can work on this site – that single feature will be the only paid option we ever introduce.
Which languages does AnyServ support?
AnyServ is available in English, Polish, German, French and Spanish, with more languages being added. Switch language instantly using the selector in the top-right corner - your preference is saved automatically. All tool results and labels update in real time.
Does AnyServ work on mobile?
Yes. AnyServ is fully responsive and optimized for all screen sizes - smartphones, tablets and desktops. Tools are designed for fast, one-handed use on mobile. No app download required - just open the browser and calculate.
How often are new tools added?
We release new tools on a regular basis. We started with 15 financial and business calculators and keep expanding into health, sport, gaming, technology and general lifestyle. Long-term goal: 200+ tools covering common calculation needs in daily life and work.
Can I suggest a tool or report an error?
Absolutely. Use the Contact page to suggest a new tool, report a calculation error, or ask about advertising and partnerships. We read every message and prioritize tool requests from users when planning the release calendar.
What is the difference between AnyServ and a regular calculator?
A regular calculator gives you a number. AnyServ gives you context - labeled results, comparisons, formatted outputs and visual breakdowns. For example, the mortgage calculator shows not just a monthly payment but total interest paid, amortization split and the effect of overpayments. Every tool is built around a real-world task, not just a formula.
