Tacit Privacy Policy

Last updated: September 28, 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 after you allow it: when you ask the AI about it and, only if you turn them on, for automatic insights and the morning read. 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.

Automatic insights

Automatic insights stay off unless you turn them on in Settings › AI access. When they are on, Tacit may send recent messages of the chats the AI can read to our analysis service without you asking, so it can suggest cards. The same rules as above apply to that text.

Morning read

Morning read is off for every chat until you turn it on in that chat's Chat info, and it needs automatic insights and AI access for that chat. For each chat where it is on, Tacit reads the chat's new messages on your device once each morning in the background, even when the app is closed, and sends them to our analysis service to build your morning card. The same rules as above apply to that text. A morning notification only says how many chats are waiting for your reply.

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) with the Apple App Attest key that proves requests come from the real app, your subscription and credit purchase records, a record of each AI request (the feature, the AI model, its size and cost, never its text), your device model, system version, language and time zone, the country and network provider of your connection, and a keyed hash of your IP address instead of the address itself, to prevent abuse. This data is linked to that random ID only and is used only to make the app work and to prevent abuse.

Card ratings

When you rate an insight card with thumbs up or down, Tacit stores which card you rated, your rating and when you gave it, with your random app ID. No message content is stored. Ratings are deleted after 180 days.

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 or a credit pack, 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.

Your rights

Depending on where you live, you may have the right to access, correct or delete the personal data we hold about you, and to object to or restrict how we use it. Your chats are only on your device, so you can view and delete them yourself in the app. To make a request about the server records, email support@tacitsense.com. Those records are tied to a random app ID, not to your name or email, so we will ask for details that let us find them, such as the date and product of a purchase.
