These terms cover your use of the Highlight Keywords browser extension and this website. By installing or using the extension, you agree to these terms.
Highlight Keywords is made and run by one independent developer, based in Pakistan, working alone. Reach that person at highlightkeywords.app@gmail.com. Purchases are taken by Gumroad, which acts as the seller of record for the payment itself, so your receipt and your card statement come from Gumroad.
You are granted a personal, non-exclusive, non-transferable license to use the extension. The Free plan is available at no cost. Lifetime Pro is an optional, one-time purchase that unlocks the Pro features described on this site for the lifetime of the product, with no recurring subscription.
Pro checks its own licence key with Gumroad from time to time in the background, so a refunded key stops unlocking Pro. If your browser cannot reach Gumroad for 45 days in a row, Pro switches off until the next successful check, then comes straight back. It needs an internet connection now and then, not all the time.
You can turn on a 14 day Pro trial without paying and without giving us anything. When it ends, the extension drops back to the Free plan: nothing is deleted, but lists past the free limit are paused until you either trim them or buy Pro. The trial is one per browser, and reinstalling does not start a new one.
Lifetime Pro is sold and processed through Gumroad. Payment, receipts, and refunds are handled under Gumroad's terms and the refund policy stated on the product page. To ask for a refund, start with Gumroad, and email us if that goes nowhere.
If you live in the EU or the UK you normally have 14 days to change your mind about something bought online. For downloads and instant-access software that right can end once delivery starts and you agree to it, which is what the Gumroad checkout asks you. Either way, statutory rights where you live come before anything written here, and in practice: if Pro is not what you expected, email and ask.
"Lifetime" refers to the lifetime of the product, not a guarantee of indefinite operation if the underlying browser platform changes. If the product is ever discontinued, the last released version keeps working for as long as your browser supports it, and the licence check will be removed or unlocked rather than left to expire and lock you out.
Do not use the extension to break the law, to infringe others' rights, or to interfere with websites in ways their owners prohibit. You are responsible for the keywords and URLs you add.
The extension is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose and non-infringement. We do not warrant that it will be error-free or work on every website.
That paragraph cannot take away a guarantee your own country gives you. Consumer law in the EU, the UK, Australia and many other places says paid software has to match its description and work reasonably well, and no wording here removes that.
To the maximum extent permitted by law, we are not liable for any indirect, incidental, or consequential damages, or for any loss of data, arising from your use of the extension. Your sole remedy if you are unhappy is to stop using it.
Nothing in this section limits liability that cannot be limited by law: death or personal injury caused by negligence, fraud, or anything else your local law protects. Where a cap is allowed and you paid for Pro, liability is limited to what you paid.
Your lists live in your browser, not with us, so keeping a copy is up to you. The extension makes automatic local backups and Settings can export everything to a file. Use it. We cannot restore anything for you, because we never had it.
We may update these terms. The current version is always posted on this page.
These terms follow the laws of Pakistan, where the developer is based. If the consumer laws of the country where you live give you rights that these terms cannot change, those rights still apply to you, and you can bring a claim in your own local courts where your law says you can.
