This notice covers the Perlatum research website at perlatum.org and its research-preview invitation list. For questions, access requests or deletion requests, contact mail@perlatum.org.

Research-preview invitations

If you request an invitation, we store your email address and the time of your request. We use the address to manage the list and contact you about the Perlatum research preview. Signing up is optional. It does not create an account or guarantee an invitation.

We keep an address while its invitation request is active. We remove it when you ask us to withdraw it or when we close the invitation list. Once an invitation has been sent, we review whether we still need the request. Write to the contact address above to ask for access, correction or removal.

Optional website analytics

Google Analytics loads only after you accept analytics. If you decline, we do not load the Analytics tag. You can change your choice with “Analytics preferences” in the footer. Withdrawing consent stops future collection on this site and clears Analytics cookies accessible to the page.

If you accept, Google receives page views, browser and device information, approximate location and usage information. We use reports to understand visits and improve the page. Google Signals and advertising personalization are disabled. We do not send your invitation email address to Analytics.

Your analytics preference is stored in this browser for up to six months. Analytics cookies set by this site are configured to expire after about thirteen months. Removing cookies, changing browsers or using a different device can require a new choice. Already collected reports are not erased by changing your browser preference.

Hosting and abuse prevention

The site runs on Google Firebase. Invitation data is stored in Google Cloud Firestore in the United States. Hosting and function services process technical request information, such as IP addresses and error logs, to deliver and protect the site.

To limit automated signups, the application keeps a hashed network identifier and a request count in a short-lived rate-limit record. It does not store the raw IP address in that record. These records expire after 24 hours and are removed by database expiry processing. People sharing a network may share a limit.

Providers and contact

Google provides hosting, database services and optional Analytics. Domain and DNS services are managed through Spaceship. Requests sent by email are processed by the email providers involved in delivering and answering them. Provider infrastructure can process data in other countries.

We do not sell the invitation list or use it for advertising. Contact us if you have a concern about how your data is handled. Depending on where you live, you may have additional rights under applicable data-protection law, including a right to raise a concern with a supervisory authority.
