Terms of Use

The short version

Optimo's image optimization is free for any purpose, personal or commercial. Video optimization, unlimited batches, target file size, and custom presets are a paid upgrade called Optimo Pro Lifetime — a single payment, no subscription. Every installation includes three free video conversions so you can see it work before you pay. It runs entirely on your computer, we collect nothing about you beyond a licence check if you buy Pro, and we make no promises that it's perfect. Use it at your own risk, keep backups of your files, and our liability is limited. The detail below spells that out.

Your license to use Optimo

We grant you a free, worldwide, non-exclusive license to download, install, and use Optimo (the "Software") on as many of your devices as you like, for both personal and commercial work. No account and no registration are required to use the free tier. This license lasts for as long as you comply with these terms.

Some features — video optimization beyond the three free conversions, more than 50 images a day, batches larger than 10 files, target file size, custom presets, and the advanced image adjustments — are enabled only by a valid Optimo Pro Lifetime licence. Working around, disabling, or circumventing that check is a breach of these terms and ends your licence.

Buying Optimo Pro Lifetime

What it costs. Optimo Pro Lifetime is a one-time payment of $19 at the current launch price (regular price $29) in US dollars. It is not a subscription: there is no renewal, and we will not charge you again. The price you paid covers the version you bought and subsequent updates to it; we reserve the right to charge separately for a future major version, and to change the price for new customers at any time.

Free video conversions. Every installation includes three video conversions at no cost, requiring no payment and no account. They are a one-time allowance rather than a time-limited trial, so they do not expire and are not restored by waiting. Once they are used, Optimo keeps working as the free tier — nothing is deleted and no file you have already produced is affected.

Who you are buying from. Payments are processed by Lemon Squeezy, which acts as the merchant of record for the sale and is responsible for collecting any applicable sales tax or VAT. Your payment details are handled by them; we never see or store your card.

Your licence key. On purchase you receive a licence key. Activating it registers that installation with Lemon Squeezy, and the app re-checks the key periodically so that a refunded or revoked licence stops unlocking Pro. Keep your key private — it is what proves the purchase. You may deactivate an installation from within the app to free the activation for another machine. Sharing, reselling, or publishing a licence key is a breach of these terms and we may revoke it.

Refunds

If Optimo Pro Lifetime isn't what you needed, you can have your money back in full within 14 days of purchase, no reason required. Reply to your Lemon Squeezy order receipt — it goes to the merchant of record who holds the payment record and can issue the refund directly — or contact us via matterdevelopment.com. We ask only that you stop using the Pro features once the refund is issued.

Because Optimo is free to use and includes free video conversions so you can evaluate Pro before you pay, we may decline repeated refund requests from the same customer, or requests that appear abusive. Refunds are issued through Lemon Squeezy to the original payment method and may take a few business days to appear.

If you are a consumer in the UK or EU, this policy sits alongside — and does not take away — your statutory right to cancel a digital purchase within 14 days.

What you may not do

Optimo is proprietary software — it is free to use, but it is not open source. You may not sell, rent, or repackage the installer as your own product, present Optimo or its name and logo as something you created, or use the Software to do anything unlawful. Beyond that, optimize away.

No warranty

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

In plain terms: we don't guarantee that Optimo will be error-free, that it will run on your specific hardware, or that any particular file will be processed exactly as you expect.

Limitation of liability — back up your files

Optimo reads, re-encodes, and can overwrite your image and video files. Encoding is lossy by nature, and no software is immune to bugs. Always keep a backup of anything you can't afford to lose before processing it.

TO THE FULLEST EXTENT PERMITTED BY LAW, MATTER DEVELOPMENT SHALL NOT BE LIABLE FOR ANY LOSS OR CORRUPTION OF DATA OR FILES, LOST PROFITS, OR ANY INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES ARISING FROM YOUR USE OF, OR INABILITY TO USE, THE SOFTWARE. OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ANY AND ALL CLAIMS IS LIMITED TO THE AMOUNT YOU ACTUALLY PAID US FOR THE SOFTWARE IN THE TWELVE MONTHS PRECEDING THE CLAIM — WHICH, ON THE FREE TIER, IS NOTHING.

Nothing in these terms limits liability that cannot lawfully be limited, including liability for death or personal injury caused by negligence, or for fraud. If you are a consumer, you keep all statutory rights that apply in your country.

Intellectual property

Optimo, including its name, logo, design, and the application binaries, is owned by Matter Development and is protected by copyright and other laws. These terms grant you a license to use the Software — they don't transfer any ownership to you.

Third-party components

Optimo bundles open-source components — including FFmpeg for video and the Sharp image library, among others. Those components remain the property of their respective authors and are licensed to you under their own terms, not these. We're grateful to the people who build and maintain them.

Downloads

Download links point to GitHub Releases. Once you click a download link you're on GitHub's infrastructure, governed by GitHub's terms of service.

Privacy

Optimo collects nothing about you and your files never leave your machine. The details are in our Privacy policy, which forms part of these terms.

Changes to these terms

We may update these terms from time to time — for example, when the Software gains new capabilities. When we do, we'll revise the "Last updated" date above. Continuing to use Optimo after a change means you accept the revised terms.
