AmpSizerTerms of use
Last updated 2026-08-10.
These terms cover ampsizer.com (“the site”). Using the site means you accept them. If you buy Pro, the Pro section below is part of your contract.
Who you are dealing with
- Operated by: maicrosites.com
- Established in: Slovakia, European Union
- Email: info@ampsizer.com
- Site: ampsizer.com
1. What the site is
AmpSizer is a set of calculators and reference pages. Everything that calculates runs in your browser and is free to use, with no account.
The results are information, not advice. We check our methods and show them on the page, but we cannot know your situation. Do not use this site as the only basis for a decision involving money, health, safety or the law. For anything that matters, ask someone qualified.
2. What you may do with it
Use it, personally or at work, as much as you like. You may link to any page and quote from it with attribution. You may embed a tool where we offer an embed option, on your own site.
You may not: scrape the site at a rate that degrades it for others; copy the
content wholesale to republish it; resell access; or present our output as your
own product. Automated access outside robots.txt is not permitted.
3. Ads
The site is paid for by advertising, served by Google AdSense. Ads are labelled. We do not control which ads are shown and do not endorse what they advertise. Pro removes them.
4. Accounts
An account holds one thing: your email address. There is no password — you sign in with a link we email you. Keep access to your inbox: anyone who can read your email can sign in as you.
You are responsible for what you put in your account. Do not use share pages to publish anything unlawful, hateful, or that infringes someone’s rights. We may remove a public share page that breaks this, and we will tell you why.
You can delete the account at any time from the account page. Deletion is immediate and permanent, including everything saved in it.
5. Pro subscription
What it includes. No ads on any site we operate; saved setups synced across devices; public share pages; embedding without our badge; email alerts on dates you choose; and the Pro tools on every one of our sites, including sites we add during your subscription. The current list is on the pricing page and is part of these terms.
Who sells it to you. Not us. Payment runs through our payment provider Polar, acting as merchant of record, and that provider is the legal seller of the subscription: it takes the payment, issues the invoice, and collects and remits VAT or sales tax for the country you are in. Its buyer terms govern the payment itself and are shown to you at checkout. We provide the service; it sells it. We never see or store your card details.
That split matters in one practical way: a refund is paid by the seller, not by us. It does not change what you can ask for — see refunds and withdrawal — and you never have to work out who to write to. Write to us and we deal with them.
Price and billing. The price is shown on the pricing page before you buy, in your own currency, with tax added at checkout. We will tell you by email at least 14 days before any price change, and you can cancel before it takes effect.
Automatic renewal. Monthly plans renew monthly and yearly plans renew yearly, automatically, until you cancel. You agree to that when you buy, and it is stated on the checkout page next to the price. Before a yearly plan renews we email you a reminder with the date and the amount. You can turn renewal off at any time from your account page in one step — online, immediately, with nobody to talk to and nothing to phone.
Cancelling. Cancel any time from your account, in one step. Pro keeps working until the end of the period you have already paid for; nothing is charged after that. Cancelling is not the same as withdrawing — see refunds and withdrawal.
If you stop paying. The account returns to Free. Nothing is deleted: public share pages become private, email alerts pause, and you can still export everything. You keep what you saved, you just cannot save more than the free limit until you subscribe again.
Availability. We aim to keep the site up but do not promise a service level. If Pro is unavailable for more than seven days in a row through our fault, write to us and we will credit or refund that period.
6. Changes to these terms
We may change these terms. If a change materially affects a paid subscription, we will email subscribers at least 14 days before it applies, and you may cancel or withdraw in that window. The date at the top says when this version took effect.
7. Liability
Nothing here limits liability for death or personal injury caused by negligence, for fraud, or anything else that cannot be limited by law. Beyond that, and to the extent the law allows, our liability to you is limited to what you paid us in the 12 months before the claim. We are not liable for indirect or consequential loss, or for loss of profit, revenue or data.
If you are a consumer, you keep every right the law of your country gives you, and nothing in these terms takes those rights away.
8. Which law applies, and where a dispute would go
We are established in Slovakia; the site is used all over the world. So this section says plainly which rule wins where, instead of naming one country and hoping you do not read on.
If you are a consumer, the law of the country you live in still protects you. Slovak law governs this contract, but only so far as it does not remove a protection given to you by the law of your own country that cannot be signed away. Where the two differ, the one that is better for you applies. That is Article 6 of Regulation (EC) No 593/2008 (Rome I), and we would rather write it down than have you discover it.
Where a case would be heard.
- We will bring a claim against you only in the courts of the country where you live. For consumers in the EU that is required by Article 18(2) of Regulation (EU) No 1215/2012; we apply the same rule to consumers everywhere.
- You may sue us either in your own country or in Slovakia, whichever suits you better.
- A standard term that pushes a consumer into the trader’s home court is unfair and a court must refuse to apply it (Océano Grupo, C-240/98). There is no such term here, and there will not be one.
If you use the site for business purposes, the consumer wording above does not apply to you: Slovak law governs and the courts of the Slovak Republic have exclusive jurisdiction.
We do not use arbitration. There is no arbitration clause and no class-action waiver in these terms. If you want a court, you can have one.
9. Complaints and out-of-court settlement
Write to us first: info@ampsizer.com. We answer complaints within 14 days, in English or Slovak. Most things end there.
If it does not end there, the out-of-court route for consumers is alternative dispute resolution (ADR):
- The competent body for us is the Slovak Trade Inspection (SOI), the residual ADR entity in Slovakia. Under Act No. 391/2015 Coll. we are obliged to cooperate with it, and we do.
- We answer any request from an ADR entity within 20 working days, as Directive (EU) 2025/2647 requires.
- If you live in another EU country, your national European Consumer Centre will take the complaint up with us for free, in your own language.
- The EU’s Online Dispute Resolution platform closed on 20 July 2025 and no longer exists. Regulation (EU) 2024/3228 repealed it. If you find a link to it anywhere on this site, it is our mistake — please tell us.
