Seeker Mobile Calc — Privacy Policy
Last updated: May 3, 2026 · Operator: Optima Sanitas (same org family as the companion SanitasSeeker / fitness-sbt work).
Introduction
Seeker Mobile Calc (the “App”) is a scientific calculator for Solana Mobile Seeker—Solana Mobile’s Android phone—with optional Solana-related tools: read-only network status, lamport/SOL math, a small on-chain transaction list preview, and optional wallet connection via the Solana Mobile Wallet Adapter (MWA). This policy describes what can leave your device and what does not.
By using the App, you agree to this policy.
What we do not collect in a central database
- The App has no first-party user accounts, no required login, and no Optima Sanitas–operated analytics SDK (e.g. no Firebase Analytics) in this release.
- Expressions you type in the calculator and local tape history are on-device unless you copy or screen-record them yourself.
Information the App may use or display
1. Network / blockchain (read-only and optional)
- RPC calls to the Solana network (default endpoints; you may paste a custom RPC URL in-app for the current session) to show slot, blockhash, balance, recent transactions, and rent information.
- Data returned by the chain (public by design) may include your wallet address when connected, transaction metadata, and fees — the same as on any public explorer.
- A SPL memo or similar test transaction is signed by you through your wallet; the network records it immutably.
2. Optional third-party (quote footer)
The app may request a short quote from a public HTTP quotation API and fall back to local text if the request fails. No wallet data is sent to that service.
3. Wallet adapter & clipboard
- MWA and your wallet app handle signing; private keys stay in the wallet/Seed Vault, not in the App’s own storage.
- If you use “sign to verify”, a display-only proof may be copied to the clipboard when the OS allows, for your own use.
How information is used
Information is used to provide calculator, local history, network status, wallet, and optional transaction-preview features; troubleshoot the App; maintain safety; and comply with legal obligations. We do not sell personal information.
Sharing, security, and retention
Calculator history and preferences are local to your device unless you export them or approve a public blockchain transaction. Public blockchain records are generally permanent and cannot be deleted by Optima Sanitas. RPC providers, wallets, explorers, quote APIs, and app stores may process data under their own policies.
We use reasonable safeguards for systems we control. Wallet private keys remain in your wallet or Seed Vault; we do not custody them.
Children
The App is not aimed at children under 13. Parents should supervise wallet and internet use.
On-chain data
Blockchain data is public; deletion of on-chain data is not possible in the way cloud accounts can be deleted. “Clearing” a list in the app only clears local UI state; it does not erase chain history.
Your choices
You can disconnect wallets, clear local app data, revoke permissions in Android settings, or uninstall the App. Depending on your location, you may have rights to access, correct, delete, restrict, or object to processing of personal information we control.

Optima Sanitas — we do not operate a separate public website for this app. Preferred: X (@optima_sanitas). Email: optimasanitas@atomicmail.io (e.g. privacy questions).
Changes
We may update this policy. The “Last updated” date and version history in this site/repo are the source of record for the document text. Material changes before any dApp Store or production release should be reflected in the App UI as required by the store operator’s agreement.
