Privacy and legal

Updated 2026-10-01. This is the same text shipped inside the extension, under More, Privacy & legal.


Privacy policy

Yochatto has no account, no analytics, no ads and no tracking. It does not sell or share anything about you, and data leaves your browser only in the cases listed below.


Kept on your device

Your settings, favorite emotes and collapsed sections are stored in your browser's extension storage. The settings panel's position and size are stored in Twitch's site storage in your browser.


Chat logs

Chat logs, off until you turn them on, keep the chat messages that arrive in Twitch chats you have open (channel, time, name and text, and which emotes a message holds) in your browser's extension database. Reading them loads the emote images from Twitch, BetterTTV, FrankerFaceZ and 7TV, as chat does. They are never sent anywhere, are pruned to the length you choose and to 200,000 messages, and can be deleted at any time from the log page or from settings.


Backups

Save to sync copies your setup to your browser account's sync storage, which your browser provider keeps like your other synced extension data. Export files and backup codes go only where you put them. Copy code writes to your clipboard only when you press it.


Requests to other sites

A few features load things from other sites. Like any web request, those sites see your IP address and basic browser details, under their own privacy policies:


• Third party emotes, off until you turn it on: emote lists from api.frankerfacez.com, api.betterttv.net and 7tv.io, and emote images from cdn.frankerfacez.com, cdn.betterttv.net and cdn.7tv.app. These requests include the name or id of the channel you are watching. When FrankerFaceZ does not know a channel, its id is looked up on gql.twitch.tv.
• GIFs, in Yochatto's emote menu: while its GIFs tab is open, the search text you type (or, with none, a request for trending GIFs) goes to api.giphy.com with the GIPHY key and rating Twitch gives the channel, the same requests Twitch's own GIFs tab makes, and the GIF images load from giphy.com. A GIF you pick is sent to chat by Twitch's own chat box, as when you send one from Twitch's picker.
• Fonts: the settings page loads font previews from Google Fonts (fonts.googleapis.com and fonts.gstatic.com). Choosing a Google font for chat, or opening a font list on the quick bar, loads fonts on Twitch pages the same way.
• Update check, on by default: every 12 hours the extension asks yochatto.com which version each store is serving, so it can tell you when yours is behind. The request carries nothing beyond what any web request does, and the answer is kept only in your browser. Switch it off in the extension under More, Updates.
• Links to this website, Ko-fi and Overlayer open only when you click them.

Bug reports

If you send a bug report, a feature request or a message, from this website or from Contact in the extension, we receive what you type in the form plus the details the extension prefilled and you chose to leave in: extension version, browser, and, for bug reports, the Twitch channel you were on and your settings (opened from the extension, only the ones that differ from their defaults). Nothing is sent until you press Send. Reports are stored in a database run for us by Neon on Vercel, are used only to fix the problem or weigh the request, and are not shared. Leave the contact field empty if you do not want a reply. To limit abuse, each report is stored with a one-way hash of the sending address; the address itself is not kept. Feature requests we take on can appear on the Requests page with their title and text only, never the contact details. Write to us through the same form to have a report removed.

Voting on the Requests page stores a random token in your browser's site storage so a vote can be taken back, and the same one-way hash of your address on the server. Neither identifies you.


Removing your data

Reset puts your settings back to their defaults. Delete all logs removes the chat logs. Removing the extension deletes everything it stored in its extension storage, chat logs included. Clearing Twitch's site data removes the saved panel position.


Changes

This policy ships inside the extension, so any change arrives with an update and is noted in the changelog. This page is kept identical to it.


Permissions

• Storage: keeps your settings, favorites and backups, and your chat logs when you turn them on.
• Twitch (twitch.tv): lets Yochatto restyle chat and add its features on Twitch. The only other page it runs on is the contact page at yochatto.com, where it fills in the report details for you.
  
  Moderation actions from the right-click menu (pin, reply, timeout and ban) are made by your own Twitch account, exactly as if you used Twitch's own buttons or chat commands.

Third party emotes

Third party emotes are made by their creators and hosted by BetterTTV, FrankerFaceZ and 7TV. Yochatto only displays them, and is not affiliated with or endorsed by those services. Each emote belongs to its creator.
