How to Install and Use DeepSeek on Android (2026 Guide)

If you want DeepSeek on Android — the official chat app, not a look-alike — the short answer is: install “DeepSeek – AI Assistant” from Google Play, or use the Android download link on DeepSeek’s own download page where Play is not an option. That gets you the same models that power the web chat: DeepSeek’s 17 October 2026 Change Log says the official web and app models were updated to DeepSeek-V4.1-Flash-1017. Copies from random APK mirrors and lookalike apps are the main risk, because an unofficial wrapper can route your prompts through someone else’s server. This guide walks through verifying the real app, installing it cleanly, checking the settings that matter, and deciding when the phone app is enough versus when you should switch to the API.

The direct answer: where to get DeepSeek on Android

DeepSeek ships one official Android client. On Google Play (checked 24 October 2026) it is listed as DeepSeek – AI Assistant with the developer shown as DeepSeek; the listing’s “About the developer” section gives the company’s Chinese name, 杭州深度求索人工智能基础技术研究有限公司, a Hangzhou address and the support address [email protected]. You have two legitimate install paths:

1. Google Play Store — search for “DeepSeek – AI Assistant” and confirm the developer name before tapping Install. This is the path to use if Play is available in your country.
2. APK from DeepSeek’s download page — the “Download for Android” button on deepseek.com/en/download links to an APK hosted on download.deepseek.com. Only use that link, never a third-party APK mirror.

If either option looks unfamiliar, cross-check against our verify official DeepSeek app checklist before tapping install. Unofficial apps that use the DeepSeek name exist on app stores and APK sites; treat anything that is not one of the two paths above as unofficial.

Is DeepSeek available in your country?

Availability varies, and DeepSeek’s Terms of Use (updated 27 March 2026) say it makes no warranty that the services are available in certain jurisdictions and that features may vary between them. Italy’s Garante ordered an urgent limitation on DeepSeek’s processing of Italian users’ data in January 2025, and several US states (Texas, New York, Virginia among them) restrict DeepSeek use on government devices. If Google Play does not show the app, that is usually a regional restriction. For the current country-by-country picture, see our DeepSeek availability by country tracker.

Minimum requirements and compatibility

The official app is a client for DeepSeek’s servers, so the requirements are modest. What matters:

• Android version: Android 7.0 or later (minimum SDK 24), according to the Google Play listing on 24 October 2026 (app version 2.7.1, updated 23 October 2026). Play shows on the listing whether your device is compatible.
• Network: inference runs on DeepSeek’s servers, so you need a working connection. Nothing runs on-device.
• Account: DeepSeek’s Terms of Use say you register an account with your email or a third-party account before using the service; its Privacy Policy mentions Apple or Google sign-in “where available”. See sign up for DeepSeek if this is your first time.

If you want local inference on an Android device (no cloud calls), skip to the “Running DeepSeek locally on Android” section below — the official app does not do that.

Step-by-step: installing DeepSeek from Google Play

1. Open Play Store and search “DeepSeek”. The official listing is “DeepSeek – AI Assistant” with the developer shown as “DeepSeek”. If the developer or title differs, stop and check our verification guide.
2. Tap Install and wait for the download.
3. Open the app and sign in with one of the sign-in options it offers, or create a new account.
4. Grant permissions only when a feature needs them. Android asks at the moment a feature first needs access (for example, to photos or files); you can reverse any decision later in your phone’s app settings.
5. Start chatting. On the app you do not pick an API model ID; you use the mode options the app shows. DeepSeek’s 13 August 2026 release notes said V4 Pro is available on the app and web via “Expert Mode”.

Step-by-step: sideloading the official APK

Only use this path if Play Store is unavailable in your region. Skip any site other than DeepSeek’s own.

1. Open a browser and go to deepseek.com/en/download directly — type the URL, do not follow a link from social media or an ad.
2. Tap “Download for Android”. The file comes from download.deepseek.com; save it to your Downloads folder.
3. If Android asks whether to allow your browser to install unknown apps, allow it for the browser only, and revoke the permission after install.
4. Open the downloaded APK and tap Install.
5. Launch the app and sign in as above.

What you get in the Android app

Feature-wise the mobile app mirrors the web chat, not the API. Key differences:

The distinction matters. The web chat and Android app keep your chat history with your account; the developer API at POST /chat/completions is stateless, and clients have to resend the full message history with each request. If you want to build something custom around the phone, you are using the API, not the app — see our DeepSeek on mobile tutorial for that path.

Using reasoning mode on your phone

DeepSeek has renamed its chat controls between releases. In August 2025 it described a “DeepThink” button for switching thinking on and off; its 2026 announcements refer instead to “Expert Mode”, and its docs do not describe today’s mode selector in detail, so use the labels your copy of the app shows. On the API, the same idea is a request parameter that returns reasoning_content alongside the final content.

When a faster, non-reasoning reply is enough:

• Quick factual lookups and short rewrites.
• Conversational back-and-forth where latency matters.
• Anything you want to paste into another app within a few seconds.

When the reasoning or expert option is worth it:

• Multi-step reasoning (maths, logic puzzles, planning).
• Debugging code you have pasted into the chat.
• Comparing options where you want a more deliberate answer.

Privacy settings worth checking on first launch

DeepSeek’s Privacy Policy (updated 10 February 2026) says it collects, processes and stores personal data in the People’s Republic of China, where the legal framework around data requests differs from many other jurisdictions. That is not a reason to avoid the app, but it is a reason to configure it deliberately.

• Training opt-out. DeepSeek’s Terms of Use say you can opt out of having your inputs and outputs used to improve the service by turning off “Improve the model for everyone”. The Terms do not say where the switch sits; look in the app’s settings, where labels can vary between versions.
• Chat history. The Privacy Policy says you can manage your chat history and copy or delete it via your settings. For deeper guarantees, review our DeepSeek privacy breakdown.
• Permissions. Grant only the permissions a feature you use asks for, and deny the rest; you can change them later in your phone’s app settings.
• App lock. If your phone offers app-level biometric locking, enable it on DeepSeek so someone picking up your unlocked phone cannot scroll your history.

Android app vs web browser: which should you use?

If you mostly chat on mobile, install the app — it keeps DeepSeek one tap away. If you are at a desk more than on your phone, the web chat at chat.deepseek.com plus a pinned Chrome shortcut is usually enough. Our DeepSeek browser vs app comparison walks through the trade-offs in detail.

Running DeepSeek locally on Android

The official app is a thin client over DeepSeek’s cloud. If you want genuine on-device inference — no account, no network, no data leaving the phone — you need a third-party runtime and a small open-weight model. Realistic options:

• MLC LLM or llama.cpp, both of which document Android builds, running a quantised DeepSeek R1 Distill checkpoint (for example the 1.5B or 7B size). Speed depends heavily on the phone’s chip and memory.
• Termux + Ollama — Termux packages Ollama, which gives you the desktop-style workflow. Heavier setup; the same model-size constraints apply.

What you will not run on a phone: the current flagship weights. The DeepSeek-V4.1-Flash-1017 repository on Hugging Face holds about 510 GB of files and DeepSeek-V4-Pro-0813 about 893 GB; those are data-centre models. For the local approach, start with our DeepSeek R1 Distill overview and the broader install DeepSeek locally tutorial.

If you need the API from your phone

Some readers land here looking to drive DeepSeek from an Android app they are building, not to chat. The surface you want is the OpenAI-compatible endpoint at POST /chat/completions against https://api.deepseek.com, with deepseek-flash or deepseek-v4-pro in the model field; the API is billed per token and separately from the free app. For setup and code, see the DeepSeek API getting started tutorial, and for current peak and off-peak rates the DeepSeek API pricing page.

Common problems on Android

Who the Android app is for — and who should skip it

The mobile client is the right starting point for casual use, quick drafting, Q&A, translation, and light coding help on the go. It is not the right tool if you need scripted automation, bulk processing, or integration with another product — those are jobs for the API. If you are still weighing general fit before installing anything, our DeepSeek beginners guide is a better starting point, and the wider set of DeepSeek beginner guides covers platform-by-platform setup.
