Tutao GmbH · Build 360.260922.0
Static checks identify review items, not a guarantee of safety.
Overview
1 finding categories to review
Tuta Mail: Secure Email (de.tutao.tutanota) scored grade A, 94 out of 100, in a static scan of version 360.260922.0 on 2026-10-08. It has no high or critical findings, and 1 lower-severity finding category across 1 occurrence. No tracking SDKs were recognised in the package. This is static analysis of a single build: it does not observe the app running and does not establish that any data is exposed.
Start with these findings
mediumCleartext (HTTP) traffic permitted1 occurrence
Interpretation & review guidance
The manifest permits cleartext (HTTP) traffic. Data sent over plain HTTP can be read or tampered with on the network; modern apps should require HTTPS.
- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.
Build & components
43 components recorded. Certificate parsing does not validate APK signature integrity.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.

Requested permission inventory (21)
Data collection & flow (privacy signal, not part of the grade)
- Personal-data permissions/identifiers appear on-device, but no third-party analytics/advertising SDKs were detected that would receive them.
This maps what the app can access (permissions it requests, identifier APIs its code references) to the third parties bundled in it. It reflects capability and SDK presence — not proof that a specific value was transmitted.
Data Safety: declared vs observed (Play label vs our analysis)
We compare the developer's Google Play Data Safety declaration with what the binary can actually do (permissions it requests, identifier APIs and third-party SDKs it ships). A mismatch is a capability signal to confirm — a requested permission is not proof of collection.
No SDKs detected by this scan.

Embed the latest grade
Embed this grade
The badge reads the latest recorded grade each time it is loaded, and links back to the full report so a reader can see the build it covers and what the scan could not see.
Grades can move when a new version is scanned or when a detector is corrected. If you would rather publish a grade that cannot change under you, link a signed Proof Capsule instead.
API users can request authenticated, scan-specific exports at /v1/scans/24d91873-e5ea-485c-b111-5d52be1b56b5/findings.sarif (also coverage.json and proof.json).
