What this website processes, and what it does not

This marketing site is statically built. There is no tracking, no analytics and no cookies.

• No Google Analytics, no Matomo, no pixel.
• No cookies, neither functional nor advertising cookies.
• No third-party embeds (no YouTube, Vimeo or maps). The fonts are served from our own server; loading the page opens no connection to a font service.

What happens when you load the site

When the site is loaded, the hosting provider records technically necessary server logs (IP address, user agent, date and time, requested URL, referrer). Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in operational security and defence against attacks). These logs are deleted automatically after 14 days.

Language

The site exists in nine languages and never switches language on its own. Your browser tells every website which languages you prefer; a script of this site compares that list on your device with the languages of the page and, if they differ, offers the matching version in a small notice. Nothing is transmitted for this. When you choose a language in the menu, in the footer or in the notice, or close the notice, the site stores the chosen language code in your browser’s local storage (key fold.lang), so that the notice does not come back. The value contains no identifier and never leaves your browser; you can delete it at any time in your browser’s settings. The documentation at docs.foldmail.app behaves the same way. Legal basis: Section 25 (2) no. 2 TDDDG (storage strictly necessary for the language choice you asked for) and Art. 6 (1) (f) GDPR.

Documentation at docs.foldmail.app

The documentation at docs.foldmail.app is delivered through Cloudflare Pages. The provider is Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA, acting as our processor (Art. 28 GDPR, on the basis of Cloudflare’s data processing agreement). When you open a page, Cloudflare processes technically necessary connection data, in particular your IP address, the requested address, date and time and the user agent, in order to deliver the pages and to fend off attacks. Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in fast and secure delivery).

Data may be transferred to the United States in the process. Cloudflare is certified under the EU-US Data Privacy Framework; the European Commission’s standard contractual clauses apply in addition. The documentation sets no cookies, embeds no chat window and no form, and loads no third-party content; the fonts are served from the same server.

Chat window and release notification

The chat window at the bottom right and the release notification form on the download page are served by the customer system of Datargo GmbH at crm.datargo.com. When the page loads, your browser fetches the chat script from there, which transmits your IP address. The chat window keeps only two values in your browser’s local storage, whether it is open and how many unread messages it shows (key __datargo_widget_…); no identifier.

If you write a chat message, or enter your email address in the form and send it, the content is transmitted to that system and stored there so that we can reply, or write to you once when FOLD is released. Legal basis for the notification: Art. 6 (1) (a) GDPR (your consent by sending the form, which you can withdraw at any time); for the chat: Art. 6 (1) (b) GDPR (steps taken at your request prior to a contract) and Art. 6 (1) (f) GDPR. We delete the address once the notification has been sent, or earlier when you withdraw your consent. Without JavaScript the form opens your mail client instead.

Email contact

If you reach out by email ([email protected], [email protected], [email protected]), we process the contents of your message and your email address to reply. Legal basis: Art. 6 (1) (b) or (f) GDPR. We keep this correspondence for as long as needed to answer your request and to satisfy statutory retention duties.

Your rights

Under the GDPR you have the right to

• Access the data we hold about you (Art. 15)
• Rectification of incorrect data (Art. 16)
• Erasure (Art. 17)
• Restriction of processing (Art. 18)
• Data portability (Art. 20)
• Object to processing based on legitimate interest (Art. 21)
• Lodge a complaint with a supervisory authority (Art. 77)

About the FOLD product app

This privacy notice covers the marketing website only. The FOLD app has no telemetry and no crash reporter. It connects to the mail servers you configure, to DNS, to your domain’s autoconfig file during setup, to Google for OAuth sign-in, and for BIMI logos to the sender’s certificate host once DMARC has passed. Sync through iCloud is optional and runs through your own Apple account. The direct download for macOS checks one static file daily for new versions, without an identifier.
