How long does ChatGPT keep your chat history?

August 20, 2026

Indefinitely while the chat exists in your account. Once you delete it, OpenAI says it leaves their systems within about 30 days — with exceptions for legal holds, and a 2025 court order made those exceptions very real. nixm has no retention window because it never writes the conversation down.

The short timeline

Undeleted chats stay. There is no automatic expiry on ChatGPT history — a conversation from last year sits in your sidebar until you remove it. Deletion starts a clock: OpenAI says removed conversations leave its systems in roughly 30 days. Temporary Chats skip the sidebar but live on the server for a similar window.

The exception that swallowed the rule

In 2025, a court order in the New York Times litigation required OpenAI to preserve conversations it would otherwise have deleted — including deleted and temporary ones — for months, over the company's objections. A retention policy describes what a company does by default. A legal hold describes what happens when someone with subpoena power disagrees. What that meant in practice.

Why "30 days" is the wrong thing to optimize

Thirty days is short enough to feel reassuring and long enough to matter. The question isn't the number — it's that a window exists at all, and that it's the vendor's to define, extend, or be ordered to suspend. Any privacy plan that depends on you deleting things, on time, forever, is a plan with a human failure mode. The delete-later habit and why it slips.

What a zero-length window looks like

On nixm the conversation is never written to a database, so there's no retention period to quote — nothing to age out, nothing to hold. What persists is a small distilled signal: your intent, a short summary, your colors. That dissolves seven days after creation, and you can end it sooner. How ephemeral AI works.

frequently asked

How long does ChatGPT store chat history?

Indefinitely while it exists in your account — there is no automatic expiry. Deletion starts a roughly 30-day removal window on OpenAI's systems.

Does deleting a chat delete it immediately?

From your view, yes. From company systems, on a schedule of about 30 days per OpenAI, and only if no legal hold applies.

Can a court extend ChatGPT's retention?

Yes — a 2025 order in the New York Times case required preservation of conversations OpenAI would otherwise have deleted, for months.

Do Temporary Chats have a shorter window?

They stay out of your history and OpenAI says they are removed within about 30 days, but they exist server-side during that window.

Is there an AI chat with no retention window?

nixm never writes the conversation to any database, so there is no window — only a distilled signal that dissolves after 7 days.

Can I try nixm without an account?

Yes — open nixm.ai and seed a signal directly; no sign-up, and nothing you type is stored.

try it now — no account, nothing stored. even the signal dissolves in seven days.
