Privacy Policy

Last updated 16 September 2026

The short version: Fenrir runs on your computer. Your stream, your viewers, your triggers and your points never leave it, except in the specific cases listed below. There is no analytics, no telemetry and no crash reporting anywhere in the application — we cannot see how you use it.

Everything that leaves your computer, at a glance

• TikTok — the LIVE connection itself, plus TikTok’s public gift list and gift images.
• Euler Stream (third party) — a signing request before the connection opens, using your free Euler key. No stream data.
• fenrirapp.com (us) — an update check each time the app opens and in Settings, carrying only the version you run; and a licence check, only if you use a licence key or sign in.
• Microsoft — with the default online voices, the text being spoken, which can include a viewer’s name or chat message. Windows’ offline voices send nothing.
• GitHub — the installer download, only when you choose to install an update.
• PaperMC, Adoptium, Thunderstore — ordinary downloads, only when you ask Fenrir to install the Minecraft server or Valheim’s BepInEx loader.
• Plutonium, IW7-Mod — only opened in your own browser. Fenrir never downloads them.

What we collect

From the application: only three things, and none of them is about how you use it. Fenrir sends no usage data, no crash reports and no device fingerprinting. It contacts us in exactly these cases:

• Checking a licence or signing in. If you use a licence key or sign in, the application asks our server whether it is valid and what plan it is on — roughly once a week, and on launch. It sends an account identifier and a value derived from your key; it never sends the key itself. Our server can see which account checked in, from which machine, and when.
• Checking for a new version. The application asks our server what the newest release is each time it opens, and again when you open Settings. The request carries no account and no identifier — just the version you are running, in the request header.
• Recording that you accepted the terms. When you accept the risk warnings and Terms of Service, and you are signed in, we record that you accepted them: your account, which version of the warnings, and when. This exists so that both of us can answer “was I told about this?” with a date rather than an argument. If you are not signed in, that record stays on your computer and we never see it.

Nothing else in the application reports to us, and none of the above tells us anything about your stream, your viewers or what you do in a game.

From this website: standard server logs kept by our hosting provider, which include IP address, browser type and the pages requested. These are used to keep the site working and secure.

If you join the waitlist: your email address, and nothing else. It is used once — to tell you when there is a build to download — and it is not a newsletter, is not passed to anyone else, and is not used to advertise to you. Ask and it is deleted.

If you buy a licence: the payment is handled by our payment provider, who acts as merchant of record. They collect your email address and billing details. We receive your email address and what you bought. We never see your card details.

What stays on your computer

Fenrir stores several things locally, in its own folder (%APPDATA%\Fenrir). None of it is uploaded:

• Your settings, keybinds, triggers, overlay configuration and sounds.
• Activity and error logs — for the current session, plus any you save to a file.
• Feedback reports, saved as files. Nothing is sent automatically; you choose whether to copy one and share it.
• The cached TikTok gift catalogue and gift images.
• Your viewers’ TikTok handles and display names, if you use the points, levels or leaderboard features. This is a list of real people’s names on your disk. It never leaves your machine, and deleting the points file removes all of it.
• A record of which version of the risk disclaimer you accepted, and when.
• If you sign in, a session token. Your password is never stored, because the application never receives one — signing in happens in your own browser.

Because you are the one holding your viewers’ information, you are the one responsible for it. Depending on where you live that may carry obligations of its own.

Third parties the application talks to

Fenrir connects to TikTok LIVE as an anonymous viewer to read public stream events. It never asks for your TikTok password and cannot post as you. It also downloads TikTok’s public gift list and the gift images from TikTok’s own servers, so the gift browser and overlays can show them.

The connection requires a signed WebSocket address, which is obtained from Euler Stream, a third-party service. Their terms and privacy practices are their own.

Text to speech sends the words to be spoken. Fenrir ships two voice engines. The default uses the same free voices Microsoft Edge uses for read-aloud, which means the text being spoken — which may include a viewer’s chat message or their display name — is sent to Microsoft to be turned into audio. No account or key is involved and nothing identifies you, but the text does leave your computer. The other engine is Windows’ own built-in speech, which is entirely offline; switching to it in Settings means nothing is sent anywhere, at the cost of the two voices a stock Windows ships with. Fenrir also falls back to the offline engine if the online one fails, so speech does not go silent mid-stream.

The application also contacts download sites when you ask it to install a prerequisite — for example PaperMC or Adoptium for the Minecraft server, or Thunderstore for Valheim’s BepInEx loader. Those are the publishers’ own sites and they see an ordinary download request. For launchers it does not install itself, such as Plutonium, it only opens the publisher’s website in your browser.

If you choose to install an update from inside the application, the installer is fetched from GitHub, where our releases are published. GitHub sees a download request like any other.

Cookies

This website uses only what is necessary to make it work and to keep you signed in if you have an account. We do not use advertising or tracking cookies.

How long we keep it

There is no Fenrir database. That is not a slogan, it is the reason this section is short: accounts live with our authentication provider, payments live with the payment provider, and the rest never leaves your machine. We are not holding a warehouse of data with a retention policy bolted on afterwards.

• Your account — email address and account identifier — for as long as the account exists. Delete the account and it goes with it.
• Your licence and which plan it is on — for as long as the licence exists, plus whatever a tax authority requires us to be able to show about a sale.
• The record that you accepted the terms — for as long as the account exists. This one is worth being plain about: it is the only thing here we would actually want to keep, because it is the record that answers “was I told about this?” for both of us. It is attached to your account, so deleting the account deletes it, and then neither side has it.
• Purchase records — held by our payment provider under their own policy. What reaches us is your email address and what you bought, kept for as long as accounting and tax rules require. Nothing has been sold yet, so today this list is empty.
• Website server logs — kept by our hosting provider for their own short window, measured in days. We do not export them, copy them anywhere, or keep our own.
• A waitlist email — until we have told you there is a build, or until you ask us to drop it, whichever is first.
• Everything on your computer — your triggers, points, logs and viewer names — for as long as you keep it. There is no clock on it and no copy of it, because we never had it.

Your rights

Depending on where you live you may have the right to ask what personal data we hold about you, to have it corrected, or to have it deleted. For us that is generally limited to your email address and purchase record, because everything else stays on your machine where we cannot reach it.

To delete what is on your computer, uninstall the application (the uninstaller asks whether to remove your data) or delete the %APPDATA%\Fenrir folder yourself.

Children

Fenrir is not intended for use by anyone under the minimum age required by TikTok’s own terms, and we do not knowingly collect information from children.

Changes

If this policy changes materially we will update the date at the top and say so in the application.
