Privacy policy

Nightshift · last updated 2 November 2026

Nightshift is a personal AI assistant used through Telegram. It is a non-commercial project that runs on one server operated by its administrator, at nightshift.omerozer.fyi, and is open to a small group of users. This policy explains what Nightshift stores and what it does with data from your Google account when you connect it.

What Nightshift stores

• Your Telegram account id and display name, to know who is writing and where to answer.
• Your messages and Nightshift's answers, the steps of each task (including tool results such as an email it read), and their cost, so you can review what the assistant did on the web view.
• Your settings: time zone, spending limits, morning brief, paper topics, notes.
• Your model API key, if you add one, stored encrypted and used only for your requests.

Each user's data is separate: other users can't see it. The administrator can see system logs for running and fixing the service.

What Google data Nightshift accesses

• Your email address, to show which Google account is connected.
• Your Gmail messages (read access): when you ask Nightshift to search or read your email, and, if you keep the inbox check on, to look at new messages and tell you about the important ones.
• Sending email: Nightshift sends an email only after you approve that specific email in the chat.
• Your Google Calendar: your calendars and events, read when you ask about your schedule, for your morning brief, or to check a date mentioned in a new email. Nightshift creates, changes or deletes an event only after you approve that specific change in the chat.

How the data is used

Google data is used only to carry out what you asked for or set up yourself, for example to answer "do I have unread emails?" or "what's on Thursday?", to write your morning brief, or to send a reply or add an event you approved. It is not used for advertising, it is not sold, and it is not used to train AI models.

Where the data is stored

On the Nightshift server (a rented virtual server), in its database and its daily backups. The long-term Google access token and model API keys are stored encrypted. Old task details are shrunk after 30 days by default; the administrator may set shorter periods.

Who the data is shared with

• Telegram carries your messages between you and Nightshift.
• The AI model provider you chose with your own API key (or, for the administrator, the one the server is set up with) receives the content needed to answer a request, such as an email you asked about, under that provider's API terms.

It is shared with no one else.

Removing access and deleting data

You can disconnect Google at any time on Nightshift's Connections page, which also revokes Nightshift's access at Google. You can also remove access from your Google account at myaccount.google.com/permissions. You can remove your model API key on the Settings page. To have all your data deleted, write to the contact below.

Google API Services User Data Policy

Nightshift's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
