POMPA End User Licence Agreement · version 1.0 · 30 August 2026
The short version: you bought a licence, not a subscription. It does not expire, it works offline forever, and everything you make with POMPA is yours. The key is personal — passing it on is the one thing that gets it blocked.
1. what this covers
This agreement is between you and Ayhan Doğan, trading as aysound (“aysound”, “we”, “us”) — the seller named on the legal notice page. It governs POMPA, the paid volume shaper: the VST3 plug-in and the standalone application, the factory presets, the licence key, and every update we release within version 1.x.
It does not cover the eleven free plugins of the AySound Suite (AyLimiter, AyCompressor, AyEQ, AyDeEsser, AyGate, AyClipper, AySaturator, AyWidth, AyGain, AyDelay, AyVerb). Those have their own, different agreement: the suite EULA. Do not read one for the other — the suite EULA grants a free-of-charge licence and says the software needs no licence file, and neither sentence is true of POMPA.
By installing or using POMPA — including in trial mode, before you have paid anything — you accept this agreement. If you do not, delete your copy.
2. trial mode
POMPA is a single download. Without a key it runs complete and without a time limit: every curve, the editor, every preset, any number of instances, all six interface languages. Two things are held back, and only two:
- every 45 seconds the effect steps aside for 2 seconds — in real time and in your bounce alike;
- saving your own presets is switched off. Loading them, and every factory preset, stays free.
Trial mode may be used for as long as you like, for evaluation. Publishing a finished production that contains the dropout is your decision and your responsibility — POMPA says so in its own window and this site says so on the product page.
3. what you get when you pay
Against payment of the price shown at the time of purchase, aysound grants you a perpetual, non-exclusive, non-transferable, worldwide licence to install and use POMPA on the computers you work on yourself — studio machine, laptop and a spare, in any reasonable number. There is no expiry date, no renewal, and no online check: the key is verified entirely on your own computer.
Everything you create with POMPA belongs entirely to you. Audio processed through it — recordings, mixes, masters, stems, bounces — is your work, and this agreement gives us no rights of any kind in it. Presets you make are yours; share or sell them freely. Commercial use is included without any further licence.
All updates within version 1.x are free. A version 2 would be a new product; owners of version 1 get a discount, not an automatic upgrade.
4. your key
The licence key is personal. It identifies your purchase, and it is the only thing standing between a paid copy and a free one. You may not publish it, sell it, lend it, or pass it to anyone else — not on a forum, not in a chat, not “just for a friend to try”.
A key that turns up in public, or whose payment was reversed, will be added to the block list of a later POMPA version. From then on that key no longer unlocks a copy that has been updated. Installations already running are not disabled remotely — we do not take software out of anyone's hands after the fact.
Lost your key? It is in the email you received when you bought it. If that is gone, write to info@aysound.com with the email address you paid with and we will send it again.
5. what you may not do
You may not rent, lease, sublicense, or resell POMPA; distribute it as part of a bundle or a preset pack; reverse engineer, decompile or disassemble it, except where that is expressly permitted by mandatory law; remove or alter any notice or identifier inside it; or circumvent, or help others circumvent, the trial-mode dropout or the licence check.
Making a backup copy of the installer for your own archive is fine, and so is reinstalling POMPA on a replacement machine as often as you need to.
6. refunds and withdrawal
Your statutory right of withdrawal, and the one condition under which it ends early for digital content, are set out on the legal notice page. Beyond that: POMPA runs completely before you pay, so you can find out whether it suits you at no cost and no risk. If you nevertheless bought it and it does not work for you — a Mac, a host that will not load it, anything at all — write to us. We would rather refund you than have an unhappy customer.
7. warranty and liability
POMPA is provided as it is. We have tested it in the hosts and on the systems listed on the product page, but no one can test every combination of Windows build, DAW version, audio interface and driver. We do not warrant that it is free of defects or that it will be uninterrupted.
Nothing in this agreement limits our liability for intent, gross negligence, injury to life, body or health, or under any mandatory product liability law. For everything else our liability is limited to the price you paid for POMPA. In particular we are not liable for lost sessions, lost recordings or lost profit. Keep backups of your projects — that is true of every plug-in, ours included.
8. term
The licence runs indefinitely. It ends if you materially breach this agreement — above all by passing your key on or by circumventing the licence check. On termination you must stop using POMPA and delete your copies. Everything you produced with it beforehand stays yours; nothing in this section reaches into your finished work.
9. data protection
POMPA never connects to the internet — not to activate, not to check for updates, not to report anything. It has no analytics and no telemetry. The key is verified on your own computer, which is also why it will still work in ten years, with or without us. What we store about your purchase, and how to have it deleted, is in the privacy policy.
10. governing law
This agreement is governed by the law of the Republic of Türkiye, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. If you are a consumer resident in the EU or the UK, this choice of law does not deprive you of the protection of the mandatory consumer rules of your own country. Place of jurisdiction, where a place of jurisdiction may lawfully be agreed, is the seat of the seller.
If a provision of this agreement is or becomes invalid, the rest stays in force.
11. trademarks
