Tacit Privacy Policy

Last updated: September 27, 2026

This policy explains what data Tacit handles and how we protect it. In short: your chats stay on your device. Our service sees a chat's text only when you ask the AI about it, only after you allow it, and only to create your answer. Tacit is developed and published by Zekby LLC ("Zekby," "we," "us," or "our").

Our approach

Tacit is privacy-first. Your conversations and analysis results are stored locally on your device. We do not operate accounts, and we do not require you to sign in.

Linked accounts

When you link a messaging account such as WhatsApp or Telegram, your messages are synced directly to your device and stored in a local database on the device. This data is never uploaded to our servers. You can disconnect and delete this data at any time from Settings.

AI analysis

When you request an AI answer, the text of the selected conversation is sent over an encrypted connection to our analysis service, which forwards it to our AI provider solely to generate the response. Tacit asks for your permission before it sends any text from a chat. You can turn AI access off for one chat in Chat info, or for all chats in Settings, and it takes effect right away. Our analysis service is stateless: conversation content is not stored, logged, or used for any other purpose on our servers, and results are returned only to your device. Our AI provider uses the text only to generate the answer and never to train AI models. To detect abuse, the provider may keep it for up to 30 days, then deletes it. If you turn on Maximum privacy in Settings › AI access, the text goes only to a provider that keeps nothing. That provider filters sensitive topics, so some answers may be blocked.

What we store on our servers

To run subscriptions and fair-use limits, our servers keep a random app ID (not your name, phone number or email), your subscription and credit purchase records, counts of the AI answers you used, your device model, system and app version, language, time zone and country, and a one-way hashed form of your IP address to prevent abuse. This data is linked to that random ID only and is used only to make the app work.

What we do not collect

We do not sell your data. We do not build advertising profiles or track you across other apps. We do not store your conversations on our servers.

Subscriptions

If you purchase a premium subscription, the transaction is processed by Apple, and subscription status is managed through our payments provider, RevenueCat. We receive only the purchase status needed to unlock premium features and credits. We never see your payment details.

Your control

You can delete individual conversations, disconnect a linked account, or remove all local data at any time. Deleting the app removes all locally stored data from your device. The server records described above contain no chat content, so deleting data in the app does not remove them. They stay tied to the random app ID so your purchases and credits keep working.
