What machgrad keeps about you. And what it doesn't.

In short

• Your messages, your assistant's memory and the AI models run on servers in Swiss data centres. Storage is encrypted.
• What leaves Switzerland: delivery through WhatsApp (Meta), and search queries to search and map services, without your name or number.
• We don't sell anything, show ads or train AI models with your data.
• At app.machgrad.ch you can download or delete your data at any time.

Who is responsible

GlobalWerk GmbH, Burgmatt 11, 6340 Baar, Switzerland. Privacy contact: Brian Christner, hallo@machgrad.ch.

What we process and why

Account: your WhatsApp number, name, language, whether you are in the beta or on the waitlist, and when you last wrote. We use this to provide the service and recognise you.

Messages and memory: what you write to the assistant, its replies, what it remembers about you, and files it creates for you. This lives in an isolated space assigned only to you, until you delete it.

Reminders, scheduled tasks and your confirmations (Yes or No before the assistant books, buys or sends anything).

Waitlist: number, email address, first name and language from the form on machgrad.ch, so we can invite you and reach you about the beta.

Settings (app.machgrad.ch): sign-in codes (valid 10 minutes), sign-ins (valid 30 days) and your browser type, so you can see where you are signed in.

Technical logs: no message content and no phone numbers (people appear only as a one-way short code). Logs are size-limited and continuously overwritten. We write no IP addresses of the settings site to any log; to prevent abuse we keep them in memory for at most one hour.

Where your data is kept

Our servers are in data centres in Switzerland (Infomaniak Network SA, Geneva). The disks are encrypted. The AI models that process your messages also run in Swiss data centres (Infomaniak). Our model gateway does not log content.

We do not use your content to train AI models.

What leaves Switzerland

• WhatsApp: messages between you and the assistant are delivered through WhatsApp by Meta (Meta Platforms Ireland Ltd.). WhatsApp's own terms and privacy policy apply as well. Meta may process data outside Switzerland, including in the United States.
• Web search: for research only the search query goes to the Brave Search API (Brave Software, Inc., USA), without your name or number. The query may still contain what you asked about.
• Place search: for restaurants, shops and opening hours only the search query goes to Google (Places API).
• Websites: when the assistant reads a website for you, it fetches it from our servers in Switzerland. The website sees our server address, not yours.
• The machgrad.ch website: pages are delivered by Cloudflare, which processes short-lived technical data to do so (for example IP address and page requested). The waitlist form goes straight to our servers in Switzerland.
• Google Analytics, only with your consent: if you choose "Allow" in the notice on the website, we load Google Analytics from Google (Google Ireland Ltd. and Google LLC, USA). It sets the cookies _ga and _ga_<ID> (up to 2 years) and sends usage data such as pages viewed, device, browser and approximate location to Google, including in the United States. We use it only to improve the website, never for advertising. If you decline, the website loads no Google script and sets no cookies. Your choice is stored only in your browser (mg_analytics), and you can change it at any time through "Cookie settings" at the bottom of every page.
• Email: if you write to hallo@machgrad.ch, Google Workspace processes the message.

For transfers to countries without adequate data protection we rely on each provider's recognised safeguards (for example the Swiss-US Data Privacy Framework or standard contractual clauses).

What we don't do

• No selling or sharing of your data with third parties, other than the providers named above for the purpose described.
• No advertising, no advertising cookies, no profiling for advertising.
• No training of AI models with your content.

How long we keep data

Your account, your assistant's memory and your reminders stay until you delete them or we end the beta. Confirmation requests expire after 30 minutes. Waitlist entries stay until we invite you or you ask us to delete them.

When you delete something, it is removed from our servers immediately. We currently keep no backups that would retain deleted data. Messages delivered through WhatsApp (Meta) are subject to WhatsApp's rules.

Managing your data

At app.machgrad.ch (sign in with WhatsApp) you can download your data as a file, delete your assistant's memory or delete your whole account. You can also write to hallo@machgrad.ch.

Cookies on app.machgrad.ch

• mg_session: keeps you signed in, 30 days.
• mg_login: ties a sign-in in progress to your browser, 10 minutes.
• mg_lang: remembers the language chosen on the sign-in page, 1 year.

All three are needed for the service. There are no advertising or analytics cookies.

Your rights

You can ask what data we process about you, have it corrected or deleted, object to its processing, and receive your data in a common format. Write to hallo@machgrad.ch. You may also complain to the Swiss Federal Data Protection and Information Commissioner (FDPIC) or, in the EU, to your local supervisory authority.

Changes

machgrad is in beta and keeps developing. If this notice changes, the date at the top changes with it. Before material changes we let you know on WhatsApp.
