Privacy Policy
Last updated: February 12, 2026
The short version: UnsubNinja is a free inbox management app. We keep it free by collecting anonymized email metadata — things like which companies send you email and where those emails land — and turning that into market research we sell to businesses. Your personal identity is never shared. We hash your email address and strip personal details before any data leaves our systems. This page explains exactly how it all works.
1. Who We Are
UnsubNinja is operated by DATECH CONSULTING, LLC, a California limited liability company. When we say "we," "us," or "our," we mean DATECH CONSULTING, LLC.
2. What Data We Collect
We want to be specific here — no vague language, no surprises.
Account Information
- Your email address (used to create your account and authenticate with your email provider)
- Name (if provided by your email provider during sign-in)
- Device and browser information (type, OS, screen size)
Email Metadata
When you connect your inbox, we access your email to provide our cleanup and unsubscribe features. We also collect metadata from your emails, including:
- Sender and recipient domains — e.g., "newsletter@example.com" → we keep "example.com" in cleartext
- Email addresses — hashed using SHA-256 (a one-way cryptographic function) so we can count unique senders without knowing who they are
- Email headers — routing information, authentication results (SPF, DKIM, DMARC), sending infrastructure details
- Placement data — which folder or tab an email landed in (inbox, promotions, spam, etc.)
- Engagement signals — whether an email was opened, deleted, or marked as spam
- Timestamps — when emails were sent and received
- Subject lines — used for inbox management features and aggregated trend analysis
Usage Data
- How you interact with the app (features used, unsubscribe actions taken)
- Performance and error data to improve the service
3. How We Keep This App Free
Let's be upfront: We monetize anonymized email metadata. This is how UnsubNinja stays free. We believe this is a fair exchange — you get a powerful inbox tool at no cost, and we get anonymized data that helps businesses understand email deliverability and market trends.
Here's exactly what that means:
- We anonymize your data. Your email address is hashed using SHA-256 — a one-way cryptographic function that turns "you@example.com" into an irreversible string of characters. We cannot reverse this process, and neither can anyone else.
- We keep sender domains in cleartext. Knowing that "company.com" sent an email is essential for deliverability analysis. This does not identify you.
- We aggregate the data. Individual email patterns are combined with data from many other users to create market-level insights — like "what percentage of emails from company.com land in spam across Gmail users."
- We sell these insights to businesses. Our B2B customers include email service providers, deliverability consultants, and brands who use this data to improve their email practices. They receive aggregate, anonymized data — never your personal information.
4. What We Do NOT Do
- We do not sell your name, email address, or any personally identifiable information
- We do not share your data with advertisers for targeted advertising
- We do not read your personal email conversations — our systems process metadata automatically
- We do not allow our B2B customers to identify individual users from the data we provide

6. Third-Party Sharing
We share data with third parties in the following ways:

- Service providers: Cloud hosting, analytics, and infrastructure providers who help us operate the service. These providers are bound by data processing agreements and only access data as needed to provide their services.
- Legal requirements: We may disclose data if required by law, subpoena, or court order, or to protect our rights, safety, or property.
7. Your Rights & Choices
