Überblick
CryptPad ist wie eine private Version von Google Docs: Du kannst gemeinsam mit anderen Texte, Tabellen oder Notizen bearbeiten, aber der Inhalt wird schon in deinem Browser verschlüsselt. Selbst das CryptPad‑Team kann nicht sehen, was du schreibst.
Warum das wichtig für den Datenschutz ist: Viele Online‑Office‑Dienste scannen deine Dokumente, um ihre Dienste zu verbessern oder Werbung anzupassen. Bei CryptPad können nur die Personen, mit denen du den geheimen Link teilst, den Inhalt lesen.
Beispiel: Du schreibst mit einer Mitschülerin eine Hausarbeit in CryptPad und schickst den Link an eure Lehrkraft, ohne dass große Konzerne euren Text mitlesen können.
