You signed up to test DeepSeek, kept it open in a tab for a few weeks, and now you want it gone — chat history, API key, billing record, the lot. Whether you have decided to deepseek delete account because you finished a project, switched providers, or want to tidy up your data footprint after the V4 Preview release on April 24, 2026, the process is more involved than tapping a single button. There are two surfaces to handle (the chat app and the developer platform), regional data-protection rights to consider, and a 2026-07-24 API migration deadline that affects anyone with legacy integrations. This guide walks through the exact steps for web, iPhone and Android, plus what to clean up first so you do not lose anything important.

The short answer: how to delete a DeepSeek account

To delete a DeepSeek account, sign in to the official chat at chat.deepseek.com or the mobile app, open Settings → Account, and choose Delete account. You will be asked to re-authenticate (email code, phone code, or the OAuth provider you signed up with), confirm the action, and acknowledge that the deletion is permanent. Developers who also use the platform should revoke API keys and zero any remaining balance at platform.deepseek.com before deleting, because the developer console and the chat profile share one identity.

That is the headline. The rest of this guide covers what to back up first, what actually disappears versus what is retained for legal reasons, and what to do if the in-app option is missing or greyed out.

Before you delete: a five-minute checklist

Account deletion is irreversible on DeepSeek’s side once it completes. Run through this list first.

• Export important conversations. The chat UI lets you copy responses or use the share/export option in each thread. There is no bulk-export button, so capture anything you will miss.
• Revoke API keys. Open the developer console, go to API keys, and delete every active key. Any application still using a deleted key will get a 401 Unauthorized error immediately.
• Zero your billing balance. If you have a paid balance left, you will lose access to it once the account is gone. Refund policy is documented on the official billing page; check it before you delete.
• Migrate legacy integrations. If your code still calls deepseek-chat or deepseek-reasoner, those legacy IDs route to deepseek-v4-flash until they are fully retired on 2026-07-24 at 15:59 UTC. Move to deepseek-v4-flash or deepseek-v4-pro on a different account if you need the service to continue.
• Note your sign-in method. If you registered with Google or Apple sign-in, deleting the DeepSeek account does not revoke the OAuth grant on Google’s or Apple’s side — do that separately in those providers’ security settings.

If you only want to stop using DeepSeek temporarily, signing out of every device and uninstalling the app is enough. Deletion is the right move when you specifically want the data record gone.

Delete a DeepSeek account on the web

The web flow is the most reliable, because every account-management screen is available in a desktop browser without app-store gating.

1. Go to https://chat.deepseek.com and sign in.
2. Click your profile avatar in the bottom-left corner, then choose Settings.
3. Open the Account tab. Scroll to the bottom — destructive actions sit below preferences and language settings.
4. Click Delete account. A confirmation modal appears with the consequences listed.
5. Re-authenticate with the verification code sent to your email or phone, then type the confirmation phrase shown in the dialog.
6. Submit. The session ends immediately and you are signed out across devices within a few minutes.

If the Delete account button is missing, the most common causes are an unverified email address, an outstanding billing balance, or an active enterprise/team membership. Resolve those first — the DeepSeek troubleshooting guide covers the specific error messages.

Delete a DeepSeek account on iPhone or Android

The mobile flow mirrors the web flow, but the menu lives behind a different icon.

1. Open the official DeepSeek app. If you are unsure you have the genuine app, the verify official DeepSeek app guide shows how to check the publisher.
2. Tap the menu (three lines or your avatar) in the top-left.
3. Choose Settings → Account → Delete account.
4. Confirm with the verification code, then submit.

Apple’s App Store policy requires in-app deletion for any app that supports in-app sign-up, so the iPhone flow must work without sending you to a website. If the option is hidden, update to the latest app version first. Platform-specific quirks for DeepSeek on iPhone and DeepSeek on Android are covered in their own guides.

What gets deleted, what is kept

Account deletion is not the same as data erasure under every regional regime. Here is the split most users see, based on DeepSeek’s published privacy notice — anchor specifics with the DeepSeek privacy guide before relying on a particular point.

If you live in the UK, EU, or another GDPR-equivalent jurisdiction, you can submit a separate data subject access or erasure request to DeepSeek’s privacy contact. That request is more comprehensive than the in-app deletion and is the right route if you specifically need the legal certainty of an erasure response.

Why people delete DeepSeek accounts

From a year of running V3, V3.2, R1 and now V4 in production, the most common reasons readers cite are:

• Switching providers. A team consolidates onto one vendor and tidies up the rest. See DeepSeek vs ChatGPT and DeepSeek vs Claude for the head-to-heads that usually drive that decision.
• Privacy posture. DeepSeek processes conversations on infrastructure subject to Chinese law. That is fine for many uses; for regulated workloads it is not, and deletion is the cleanest exit.
• Regional restrictions. Italy’s data-protection authority blocked the app in January 2025, and several US states have restricted its use on government devices. Personal users in those contexts often prefer to remove the account outright.
• Project finished. A one-off evaluation account that no longer needs to exist.

If you change your mind: closing without deleting

Permanent deletion is final. If you only need a break, lower-risk alternatives include:

• Sign out and uninstall. The account stays dormant but recoverable.
• Delete individual conversations. Each thread has its own delete option in the chat list.
• Disable training use. If you previously opted in to having conversations sampled for training, switch the toggle off in Settings → Data controls. This stops future use without removing the account.
• Reset the password. If the original concern is suspected unauthorised access, the reset DeepSeek password guide is faster than starting over.

Developer-side cleanup: keys, billing and the API

If you used the developer platform, the chat-side deletion is only half the job. The platform stores API keys, an organisation/project structure, and billing records that need explicit handling.

1. Revoke API keys

Sign in to platform.deepseek.com, open API keys, and click Delete next to each key. Any application still calling DeepSeek with a deleted key will fail authentication on the next request to POST /chat/completions, the OpenAI-compatible endpoint at https://api.deepseek.com. The full key-management workflow is in the get a DeepSeek API key guide.

2. Confirm no scheduled jobs are running

Check cron jobs, serverless functions, CI runners, and any context-caching workflows that ping DeepSeek. The API is stateless — every request resends the full conversation — so a “quiet” job can still be billing tokens until it is stopped. If you are unsure, the DeepSeek status checker can confirm whether traffic is still hitting the platform.

3. Migrate before the legacy ID retirement

If you keep using DeepSeek under a different account, swap any remaining deepseek-chat or deepseek-reasoner calls for deepseek-v4-flash or deepseek-v4-pro before 2026-07-24 at 15:59 UTC. Both V4 IDs sit on the same https://api.deepseek.com base URL, share a 1,000,000-token context window with output up to 384,000 tokens, and accept thinking mode as a request parameter (set reasoning_effort="high" with extra_body={"thinking": {"type": "enabled"}}) — when thinking is enabled, the response carries reasoning_content alongside the final content. A minimal Python migration looks like this:

from openai import OpenAI
client = OpenAI(base_url="https://api.deepseek.com", api_key="...")
resp = client.chat.completions.create(
    model="deepseek-v4-flash",  # was "deepseek-chat"
    messages=[{"role": "user", "content": "Hello"}],
)

That is the only change to call sites. Everything else — temperature (use 0.0 for code, 1.3 for general chat per DeepSeek’s guidance), top_p, max_tokens, JSON mode, streaming, tool calling — works identically. The V4 release notes are summarised in the DeepSeek V4 release date roundup.

4. Drain the billing balance

A positive balance does not transfer between accounts. Either spend it down, or check the refund process on the billing page before deleting. Note that the off-peak API discount that existed before September 5, 2025 is not coming back — current pricing is the only pricing.

Re-creating an account later

You can register again with the same email after the account has been fully purged on DeepSeek’s side, which typically takes up to 30 days. The new account starts fresh: no chat history, no saved prompts, no API keys, and no carry-over of any granted balance from the old account. If you signed up via Google or Apple sign-in, simply tapping the same OAuth button creates a new DeepSeek profile linked to the same identity.

The DeepSeek account setup guide walks through the registration flow if you decide to come back, and the DeepSeek login guide covers the sign-in surfaces.

If deletion fails

A small number of deletion attempts get rejected. The fixes:

• “Outstanding balance” error. Settle or zero the balance in the billing console.
• “Pending invoice” error. Wait for the current billing cycle to close, then retry.
• “Account is part of an organisation” error. Leave the team or have an admin remove you first.
• Verification code never arrives. Check spam, then try the alternate channel (phone instead of email or vice versa). Some regions have SMS delivery delays.
• The button is greyed out. Update the app, or switch to the web flow which exposes more error messaging.

If none of the above resolves it, contact support through the in-product help link with your email and the timestamp of the failed attempt. For a wider list of related fixes, the DeepSeek troubleshooting page is the right next stop, and you can browse other walk-throughs in the DeepSeek beginner guides hub.

Alternatives worth considering before you leave

If the trigger is cost or capability rather than privacy, it is worth knowing what you are giving up. As of April 2026, deepseek-v4-flash lists $0.028 cache-hit / $0.14 cache-miss / $0.28 output per 1M tokens, and deepseek-v4-pro lists $0.145 / $1.74 / $3.48 — among the cheapest frontier-tier chat APIs for the V4-Flash tier, though specific competitor rates change frequently and should be checked on the providers’ own pricing pages before deciding. The DeepSeek alternatives page lists where to look next if you do leave.
