This policy explains what the MPC waitlist app collects, why, how long it is kept, and what you can ask us to do about it. It covers this app only.
Who we are
The app is operated by Bolor Geo MPC Corp., the issuer of the MPC project. You can reach us through the contact channels listed on our main site.
What we collect
We do not use advertising trackers or visitor analytics. We do not sell personal data.
| Data | Why | How long |
|---|
| Email address | To send your sign-up code and confirm your place on the waitlist | Kept while your entry stands |
| Wallet address | To identify your entry, check eligibility, and record on-chain actions | Kept while your entry stands. On-chain records are permanent |
| IP address | Stored only as a one-way hash, to limit abuse of sign-up and sign-in | Up to 24 hours |
| On-chain activity | Check-ins, quests and badges you complete | Permanent and public on the blockchain |
| Quiz and quest activity | To show your progress and award energy | Kept while your entry stands |
| Session and server logs | To keep you signed in and to investigate faults | Session 24 hours. Logs follow our hosting provider |
Optional information
Some quests may ask for optional details such as your country, year of birth or gender. Answering is never required. Each item is asked for separately, nothing is ticked in advance, and you can withdraw, correct or delete your answer at any time.
Before you answer, we show you what the item is used for, how long it is kept, and what happens if you decline.
Who else receives it
We use service providers to run the app: email delivery, blockchain access, wallet connection and hosting. They receive only what they need for that task, and some of them operate outside your country.
Records on the blockchain
Actions you take on chain, such as a check-in or a completed quest, are written to a public blockchain. Those records are permanent. We cannot edit or delete them, and neither can anyone else. Please keep this in mind before acting on chain.
Your choices
You can ask us for a copy of what we hold about you, ask us to correct it, ask us to delete it, or withdraw consent you gave for optional items.
Two limits apply. On-chain records cannot be deleted, as described above. And where we must keep something to run the waitlist fairly, we will tell you why rather than delete it quietly.
Children
The app is not intended for children. If you tell us you are below the age where consent is valid in your country, we will not use optional details you provided.
How we protect it
Sessions are encrypted, IP addresses are stored only as hashes, and secrets are never written to logs.
Changes
If we change this policy we update the date at the top. Where the change affects something you consented to, we will ask again.
