What is MATE?
MATE is a privacy-first AI assistant built and operated in Switzerland by Swisswise GmbH. Use it to write, research, translate, plan and work with documents and images across iPhone, iPad, Android, Mac and the web. MATE does not sell conversation content or use it to train models.
Who is MATE for?
MATE is for anyone who wants useful AI with privacy at the centre, from everyday writing and research to confidential professional work. It is simple to start, and organisations can contact us about private deployment options.
Where are my chats and Memory stored?
Your chat history and Memory are stored on the device or browser where you create them and are not synced through your MATE account. You can turn history off or choose automatic deletion after 7, 30 or 90 days.
Does MATE retain my conversation content?
No. In MATE Cloud Mode, MATE processes the content needed to answer your request and does not retain the conversation content afterwards. Account, billing and support records are kept separately only as needed to provide the service and meet legal obligations. In On-device Mode, the request stays on your device.
Is my data sold or used for model training?
No. MATE does not sell your conversation content or use it for advertising, profiling or model training.
Can I use MATE without an internet connection?
Yes. Sign in and complete the one-time On-device setup while online. You can then use On-device Mode without a connection, with your conversation content staying on your device. Features that need live online information are available in MATE Cloud Mode.
How do I set up On-device Mode?
Open Settings, choose On-device Mode and follow the steps shown for your device. MATE confirms when setup is complete, and you can change the setting at any time.
How do I sign in?
Sign in using the options shown on your platform. Your account carries your access and plan across supported devices; it does not sync your chat history.
What do the plans include?
The free plan lets you try MATE. Paid plans include higher usage allowances and additional features such as On-device Mode, image generation, Custom Mates and Expert Mode. See Pricing for current details.
Can I use On-device Mode on Android?
Yes. Open Settings, choose On-device Mode and follow the setup steps. MATE clearly shows when On-device Mode is active.
Can organisations use a private deployment?
Yes. We offer private deployment options for organisations with specific privacy or governance requirements. Contact our team to discuss the right setup.
How do I use voice?
Tap the microphone to dictate, review the transcript, then send. MATE requests microphone access only when you choose voice input. Choose an on-device voice option where it is shown.
How does Web Search protect my privacy?
Turn on Web Search when you need current information. The search request goes out without your account and without your identity — nobody can link it to you, not even us. The sources used are listed right with the answer.
How do I protect chats on my device?
Switch on App Lock in Settings, under Privacy and Security, and follow the setup steps shown on your device. Save the recovery file somewhere secure so you can regain access if you forget your code.
Which languages does MATE support?
MATE supports a wide range of interface and answer languages and follows your device language on first launch. You can choose a fixed answer language or let MATE follow the language you use.
How does MATE support accessibility?
MATE follows your device's accessibility preferences, including text size, bold text, increased contrast, reduced motion and screen-reader settings. You can also adjust chat text size in Appearance.
How do I delete my data?
Open Settings, then Data, to delete chats, Memory and generated images from the current device, turn history off or choose automatic deletion. Open Settings, then Account, to delete your account. Cancel any active subscription separately in the store or billing portal where you purchased it.
Where can I use MATE?
MATE is available on iPhone, iPad, Android, Mac and the web. Each version is designed for its platform; visit Download for current availability and follow the feature labels shown in the app.
