Tiho is a browser extension that filters social media feeds. It's made by VIDEZ s.p., Slovenia ("we"). Contact: support@usetiho.com.
The short version

Free feed cleanup runs entirely in your browser. Optional technical diagnostics are off unless you allow them.
AI filtering (Tiho Pro) sends the posts in your feed to our server to be classified. We don't store them.
We never sell your data, show you ads, or use your posts or votes to train models.


Free feed cleanup

Hiding ads, suggested accounts, trends and similar page elements happens locally in your browser. Your settings are stored in your browser's extension storage. You don't need an account. Without optional diagnostics, cleanup sends no requests to Tiho. If you allow diagnostics, the extension sends technical breakage counters and its version, without post content. You can turn this off in Tiho settings; in Firefox you can also change optional data permissions in the Add-ons Manager.
AI filtering

When AI filtering is on, the extension sends each post in your feed to our server (a Cloudflare Worker) for classification:

the post text, author name and handle, a quoted post, link card and poll text, and engagement counts;
your filter preferences: the categories you hide, your taste notes, your rules, and short summaries of your most similar past votes.


Our server sends this to an AI model through Cloudflare, which returns probabilities (for example "is this rage bait?"). The model is TypeSafe's Jev, reached through Cloudflare AI Gateway with zero data retention, or a model on Cloudflare Workers AI. We use the result to answer your request and then discard the post content. We don't store post content, and we don't write it to logs.

"Learn from my votes" sends vote summaries and relevant past post data, preferences and rule questions, in the same way, to write and test rules for your filter. Your saved votes, rules and decisions about which posts to hide remain in your browser. Firefox asks separately for account and AI data permissions; removing AI permission pauses transmission and filtering while local cleanup continues.
Launch notifications

If you request a launch email, we store your email address, chosen browser and signup date in our Cloudflare database. We copy your email address and chosen browser to Resend to manage the launch audience and deliver that email. We use your consent to send one availability email for each browser you choose, not a newsletter. No account is created. We remove the entry after sending that browser's launch email, or when you withdraw consent by emailing support@usetiho.com. Resend also provides an unsubscribe link in launch emails and may retain a suppression record to respect your choice. We don't send a confirmation email when you join.
Your account

Account data: your email address, name and, with Google sign-in, your profile picture URL.
Sessions: a session record with the IP address and browser user agent you signed in from, kept until it expires (up to 60 days) or you sign out.
Usage: how many posts were classified per day and how much model capacity they used, to apply fair-use limits.
Service metrics: per request, your account ID, the type of request, the model, timing and size. No content. Kept for up to 3 months to measure cost and reliability.
Optional breakage reports: technical counters such as "a page element wasn't found" and the extension version, sent only when you allow diagnostics, so we can fix changes to the site. No post content is included.


Payments

Payments are processed by Stripe, which acts as the merchant of record (shown as Link at checkout). Stripe collects your payment details and billing address under its own privacy policy. We receive your subscription status, not your card number.
This website

usetiho.com uses Cloudflare Web Analytics to count page views and measure load times. It doesn't use cookies, doesn't store anything in your browser, and doesn't follow you across other sites. We see totals such as visits per page, country and browser type, not individual visitors.

We also use DataFast to measure website visits and traffic sources. DataFast uses cookies to recognize returning visitors. We also report public crawler requests to DataFast, including the requested page path, crawler user agent, IP address and response status. Query strings and account/API routes are excluded. See DataFast’s privacy policy for details.

Changelog entries may include videos hosted by YouTube or Vimeo. These players load only when you choose to load a video; that connects your browser to the provider, which may receive your IP address and browser information under its own privacy policy. Screenshots and video files hosted by Tiho load from our website.
