Local mode
Sample DNA analyzes audio in your browser. Local samples, analysis, presets and trash remain on your device unless you deliberately enable Encrypted Backup or export a backup.
Optional Encrypted Backup
Encrypted Backup requires sign-in through the active authentication provider, acceptance of the current policies and a passphrase you choose. Your browser encrypts filenames, metadata and audio with AES-256-GCM before upload. The passphrase and encryption key are not sent to Sample DNA. If you lose the passphrase, the encrypted cloud files cannot be recovered.
Beta feedback
Feedback is optional and requires sign-in plus an explicit confirmation before sending. Reports may include your written message and a limited DNA snapshot such as detected and corrected BPM, key, mood, texture, subgenre, duration and mutation name. Audio, filenames and Encrypted Backup passphrases are excluded. The master account can review and resolve reports.
Aggregate beta usage
For signed-in beta accounts, Sample DNA keeps daily aggregate counts for core actions such as completed analyses, mutation renders, mutation ratings and downloads. These counters do not contain audio, filenames, DNA measurements or account identifiers and are shown only as combined 30-day totals.
Stored information
The service stores a one-way hash of your sign-in email for account isolation, encrypted sample data, encrypted metadata, file size, timestamps, display name, account role, account status, policy acceptance, rate-limit counters and feedback you deliberately submit. Closed-beta invite codes are stored only as hashes with labels, expiry and use counts. Encrypted audio is stored in object storage; account, feedback and file records are stored in the application database.
Master account
The Sample DNA master account can see tester display names, account status, invite label, last active time, private tester notes, file count, aggregate storage use and submitted feedback, and can suspend or restore tester access. Because sample content and filenames are end-to-end encrypted, the master account cannot read them without the tester's private passphrase.
Control and deletion
You may delete individual cloud files or delete your Sample DNA cloud account and its entire Encrypted Backup dataset from the app. Full cloud-account deletion also removes submitted feedback and associated rate-limit records. Device-local Trash and exported backups are separate and remain under your control. Operational backups may take a limited period to expire.
Security and limits
Cloud routes require authenticated identity and enforce per-user ownership checks, quotas and rate limits. Encryption reduces exposure but no online service can guarantee absolute security. Do not upload unlawful content or information you are not permitted to store.
Policy changes
If this policy changes materially, Encrypted Backup will require acceptance of the new version before additional syncing or restoration.
