Last updated: June 23, 2026. This Data Policy describes how
Microset handles data in practice. It complements the
Privacy Policy, which covers your rights. On-chain vs off-chain data
Microset is non-custodial and blockchain-based, so data lives in two places:
| Where | What | Properties |
|---|
| On-chain (Solana) | Wallet address, predictions, claims, market state | Public, permanent, not controlled by Microset |
| Off-chain (our backend) | Account/session data, app preferences, support records | Private, stored by us, deletable on request |
What we store off-chain
| Data | Purpose | Retention |
|---|
| Wallet public address | Link activity to your session and profile | While the account is active |
| Sign-in signature / session token | Verify wallet ownership and keep you signed in | Session duration |
| Prediction / claim history (cached) | Display your positions and history in the UI | While the account is active |
| Device & log data | Security, debugging, abuse prevention | Up to 12 months |
| Support correspondence | Respond to and track your requests | While the account is active |
What we never collect
- ❌ Private keys
- ❌ Seed / recovery phrases
Sub-processors
We use third parties to operate the Service. The current list:
| Provider | Role | Data shared |
|---|
| Privy | Wallet connection & authentication | Wallet address, authentication signals |
| Solana RPC provider | Read chain state / submit transactions | Wallet address, transaction data |
| Database provider (MongoDB) | Store off-chain application data | Off-chain data listed above |
| Hosting provider (Railway) | Run the backend API | Operational data |
Storage and security
- Sensitive credentials (such as authentication tokens) are held in encrypted storage.
- Access to off-chain data is restricted to authorized personnel and systems.
- All data in transit is encrypted (HTTPS/TLS), with restricted access to production systems and regular backups.
Data retention and deletion
We keep off-chain data only as long as needed to operate the Service and meet legal
obligations, then delete or anonymize it. You can request deletion of your
off-chain data by contacting tech@microset.io.
On-chain data (your wallet address and transactions) is public and permanent. It
cannot be edited or deleted, including on deletion requests.
International processing
Data may be processed in countries other than yours, with appropriate safeguards
where required.
Changes
We may update this Data Policy. Material changes will be posted here with a new
“Last updated” date.
Data questions or deletion requests: tech@microset.io.
