The terms for using Fenn.

These terms apply to the Fenn app for Windows, your Fenn account, the plugin marketplace and the website at fenn.click (together, “Fenn”). By installing Fenn, creating an account or using the website, you agree to them. If you don’t agree, don’t use Fenn. Last updated 11 November 2026.

Who can use Fenn

You must be at least 13 years old, or the minimum age to consent to data processing where you live if that is higher. If you use Fenn for an organisation, you confirm that you can accept these terms for it.

Your license to use the app

Fenn is proprietary software. It is not open source. We give you a personal, non-exclusive, non-transferable, revocable license to install and use Fenn on Windows PCs you own or control, as these terms allow. We, and the people we license from, keep all rights to Fenn, including its code, design, name and logo.

You may not:

• copy, sell, rent, sublicense or redistribute Fenn or its installer, except as these terms allow,
• decompile, reverse engineer or take apart Fenn, except where the law allows it despite this restriction,
• remove, bypass or tamper with sign-in, feature locks, license checks or update checks,
• use the Fenn name or logo in a way that suggests we made or endorse something we didn’t.

Fenn includes open-source components under their own licenses. Those licenses still apply to those components, and nothing in these terms limits them.

The plugin protocol, the plugin docs and the plugin SDKs (fenn.py and fenn.js) are there so you can build plugins. You may use them to make, share and sell your own plugins.

Your account

The notch needs a free Fenn account. Give a real email address and keep your password to yourself. You’re responsible for what happens under your account, including on every PC signed in to it. If you think someone else has access, change your password and sign out the PCs you don’t recognise on your account page. You can delete your account there at any time; the privacy policy lists what that removes.

Acceptable use

Don’t use Fenn or the website to:

• break the law, or infringe anyone’s rights, including copyright and privacy,
• attack, overload, scrape or probe our servers, or try to get into accounts or data that aren’t yours,
• make accounts in bulk, or share one account so that people who haven’t accepted these terms can use it,
• post reviews, suggestions or plugins that are spam, misleading, hateful, harassing, sexual, or that contain malware,
• record or mirror other people’s screens or devices without their permission.

Plugins

Plugins are separate programs written by other people. A plugin runs on your PC with the same access you have, so only install plugins you trust. We check each submission against Fenn’s plugin rules and record the exact commit we reviewed, but we don’t audit every line, and we aren’t responsible for what a plugin does. Plugins made by others are covered by their authors’ terms and licenses, not by ours.

When you submit a plugin, you confirm that:

• you wrote it or have the right to publish it, and its repository says under which license,
• it does what its listing says, and nothing hidden or harmful,
• you allow us to show its name, icon, description, repository details and code on fenn.click, and to let Fenn install it.

We can refuse, hide or remove any plugin, review or suggestion, at any time and for any reason, including reports that it breaks these terms.

You keep the rights to the reviews and suggestions you write. You allow us to show them on fenn.click with your name for as long as they stay up. You can delete them, or delete your account to remove them all.

Supporter package and paid features

Some tools, like Hey Fenn, need the supporter package after a free period. You buy it on Gumroad, which is the seller of record: its terms cover the payment, taxes and receipts. Buy with the same email as your Fenn account (or from the button on your account page) and it unlocks on every PC signed in to that account.

If something you bought doesn’t work, email [email protected] and we’ll fix it or refund you. Refunds also follow Gumroad’s refund process and any rights you have under the consumer law where you live. A refunded or charged-back purchase removes what it unlocked.

Which tools are free and which are paid can change. We won’t take away something you already paid for without offering a fair alternative or a refund. Paid tools may need a recent version of Fenn to keep working.

Updates and changes

Fenn updates itself automatically to fix bugs, close security holes and add features. Old versions can stop working with our servers, and some tools can lock on versions we no longer support. We can change, add or remove features of Fenn and the website at any time.

No warranty

Fenn is provided “as is” and “as available”. As far as the law allows, we make no promises that it will be uninterrupted, error-free, secure or fit for a particular purpose, or that our servers will always be reachable. Fenn changes how Windows’ taskbar and windows behave; keep backups of your important files, as with any software.

Limits on liability

As far as the law allows, we aren’t liable for any indirect, incidental, special or consequential damages, or for lost data, profits or time, coming from your use of Fenn, its plugins or the website. Our total liability for any claim about Fenn is limited to the greater of what you paid us in the 12 months before the claim and 10 US dollars.

Some places don’t allow these limits. Where that’s the case, they apply only as far as the law allows, and nothing here takes away rights you have as a consumer that can’t be waived.

Ending these terms

You can stop using Fenn at any time: uninstall it and, if you like, delete your account. We can suspend or close an account, or stop providing Fenn, if you break these terms, if the law requires it, or if we stop running Fenn. If we shut Fenn down, we’ll give reasonable notice where we can. The sections on the license limits, plugins, no warranty and liability still apply after these terms end.

Changes to these terms

We may update these terms. When we do, we change the date at the top. For changes that matter, we’ll tell you in Fenn or by email before they take effect. If you keep using Fenn after that, you accept the new terms.
