Welcome to MiProse (the "Service", "we", "us", or "our"). We are deeply committed to protecting the privacy, secrets, and raw emotional content you entrust to us. This Privacy Policy explains how we collect, protect, and handle your information across our global platform.
1. Information We Collect and How We Use It
To safely deliver your future memories, we collect the minimum required data:
- Your Name / Nickname: To personalize your future letter and the AI response.
- Your Email Address: The vital shipping destination where your capsule will be delivered 90, 180, or 365 days later.
- Your Letter Content & Uploaded Photos: The sacred emotional core of your capsule.
- Transaction Data: Processed securely via Stripe. We do not store your raw credit card numbers on our servers.
2. Ultimate Data Security & Encryption
Because your letters contain deep personal thoughts, privacy is our top engineering priority:
- Content Encryption: All letter contents are strictly encrypted both in transit and at rest within our secured database. Nobody—including our team—can browse or read your active sealed letters.
- Automated Delivery: Your letters are unsealed and compiled strictly by automated code triggers at your chosen future date and midnight timestamp.
3. AI Processing & Zero-Data Retention Policy
Your letter content is processed via the Anthropic Claude 3.5 Sonnet API to generate your personalized "Old Friend's Reply."
- No AI Training: We utilize enterprise-grade API connections. Your private stories, letters, and emotional vulnerabilities are NEVER stored, retained, or used by us or third-party AI entities to train machine learning models. Your data is processed dynamically in-memory and safely delivered back to you.
4. Data Retention and Deletion
Your data remains sealed in our secure database until your designated delivery date. Once your capsule is triggered and successfully delivered to your inbox, you may request the complete permanent erasure of your record from our servers at any time by contacting our support channel.
5. Do you record my location when I write the letter?
To beautifully recreate the temporal atmosphere of the moment you sent your letter, our system notes the rough city and country of origin via your network IP at the exact moment of submission. We never request or track your precise GPS coordinates. This spatial tag is securely sealed as a pure emotional component of your time capsule and will only be shown back to you upon decryption. We strictly pledge never to use this data for any third-party tracking, profiling, or commercial purposes.
