MailShield Guardian — Privacy Policy
MailShield Guardian is built by Glippin Toys, LLC. We respect your privacy.
Summary
- No account, no email, no password. MailShield signs you in anonymously.
- Suspicious content you submit (photos of mail, pasted texts, emails, phone numbers) is processed in-memory for AI analysis. The raw content is not stored long-term.
- Anonymized scam fingerprints (the pattern of the scam, not your personal data) contribute to the community database so the next person who gets the same scam gets a fast verdict.
- No advertising. No third-party trackers.
What we collect
| Data | Why | Retention |
|---|---|---|
| Anonymous user ID | Tie scans, premium status, family to one identifier | Until account deleted |
| Scan result (verdict + summary) | Your scan history | Until you delete |
| Anonymized scam fingerprint | Community scam database | Indefinitely (de-identified) |
| Push token (optional) | Send local scam alerts you opt into | Until you uninstall |
| Crash reports | Diagnose bugs | 90 days |
What we never collect
- Names, emails (yours), phone numbers (yours), mailing addresses
- The raw content of the suspicious mail, texts, or emails you scan (used in-memory only, not persisted)
- Anything from advertising or tracking SDKs
The fingerprint engine collective
The asset that makes MailShield smarter than a single AI scan is the proprietary anonymous scam fingerprint database that every user contributes to. When you scan a suspicious item, MailShield extracts a fingerprint — the scammable signature (phone number, sender pattern, URL, claim DNA) — strips out your personal context, and adds it to the shared collective. Future users who encounter that fingerprint get a faster, more confident verdict.
AI models in MailShield learn from the aggregated fingerprint collective, not from your individual scans. The verdict you see is the collective intelligence of every prior anonymous contributor.
When you delete your account, your scan history is removed. Past fingerprints contributed to the collective were de-identified at the moment of contribution and remain in the shared dataset — they were never linkable to you in the first place.
