Privacy policy

Applies to the Tiho browser extension 0.1 and to this website. Last updated: 11 October 2026.

Short version: Tiho filters live chat on your own device. It has no server, no account, no analytics and no telemetry. Chat messages never leave your computer. This page explains exactly what the extension reads, stores and sends.

What Tiho reads

Tiho does not read anything else on those pages and does not run on any other website.

Where the work happens

Every message is classified inside your browser by an AI model that ships with the extension, running on your graphics card (WebGPU) or processor (WebAssembly). No code or model is loaded from the internet, and no message text is sent anywhere.

What Tiho stores

WhatWhereHow long
Your settings, presets, rules, custom filter questions and per-channel stream contextYour browser's extension storage (this browser only, not synced)Until you remove the extension
"Not spam" feedback: the message text, author, platform, channel and the original decision, at most 500 entriesYour browser's extension storageUntil you remove the extension. Never uploaded.
The model's current statusBrowser session storageUntil the browser closes
The filtered log (at most 200 messages) and the questions inbox (at most 100)Memory of the chat tabUntil you close or reload the tab

Removing the extension deletes all of it. Nothing is stored on any server, because there is none.

What Tiho sends over the network

No chat text leaves your computer. The extension has no server to talk to. The only network traffic it can make involves the optional Tiho Engine:

Separately, when the side panel cannot get the Engine's status from the extension itself, it may ask the Engine address directly whether the Engine is running. That request contains no chat text and, with the default address, never leaves your computer.

The 127.0.0.1 and localhost entries in the extension's permissions exist only for Tiho Engine.

Tiho Engine

The optional Engine is a separate app that runs on your computer. It listens only on 127.0.0.1, accepts requests only from the browser extension and from localhost, keeps message text only in memory and never logs it. On first start it downloads its AI model and runtime from Hugging Face and GitHub.

What we never do

Training data

The model was trained on public live-chat messages collected without an account, together with permissively licensed public datasets. Some message texts (without author names) were labelled by AI annotators. Raw chat logs are kept privately, used only to build training data, and never published or shared; only the trained model is distributed.
