MASTR began by publishing scam warnings and investigating the people, wallets and financial interests behind them. The work now includes onchain investigations, external security assessments, tools, apps and educational material.
The operator’s identity remains private following threats connected with this work. Published findings include supporting evidence and reproducible methods where disclosure allows it.
The work helps users and teams examine risks before making decisions.
MASTR creates security information, onchain research, learning content and practical tools for crypto users.
The $MASTR App uses accounts, wallet connections and messaging. MASTRpass stores its encrypted vault locally on the device.
MASTRpass is the offline vault app from MASTR. It does not need a MASTR account and does not connect to the $MASTR App services.
MASTRpass reduces specific risks. It does not remove your responsibility for backups, device security and careful verification.
Store availability and a verified APK signature do not replace an independent audit. Unless a specific audit report and scope are provided, do not treat a release, score or security feature as certification.
Keep multiple verified encrypted backups and store the recovery key separately and safely.
MASTRpass and linked MASTR content are not investment, legal or tax advice and do not guarantee protection from scams or loss.
Offline tools inspect structure and cryptography, not current blockchain state, revocation lists, malware databases or reputation.
Verify the domain, filename, SHA-256 and signature where available. Do not open a mismatched or unofficial file.
No analytics cookies, accounts or tracking pixels. The language choice is stored only in your browser.
MASTRpass does not sign, broadcast or simulate blockchain transactions. It cannot establish current balances, ownership, revocation status or online reputation. Decoding or validating a signature does not make a transaction or file trustworthy.
These tools and publications are not financial, investment, legal, tax or insurance advice. You remain responsible for your decisions. No recovery outcome, savings, transaction completion or protection against loss is guaranteed; mandatory legal rights remain unaffected.

These terms describe use of MASTRapps.com and the applications presented here. MASTR operates under the MASTRlabs name. Questions about the website, app releases or these notices can be sent to info@mastrapps.com. Each app has its own capabilities and limitations; a statement about one app does not automatically apply to another.
Download the three listed Android APKs from MASTRapps.com or obtain the apps through the Solana Mobile dApp Store on Seeker. Other products use the official store or web links on their own pages. Availability on one platform does not imply release on another. Verify the file version, SHA-256 and signer where possible. A valid signature confirms file integrity under its signing key, not an independent security audit or a guarantee of safety.
Downloading the three APKs is free. MASTRpass Pro is also free to use. MASTRsweep and MASTRsender charge the service fees disclosed on their product pages, in addition to applicable network costs. Review the transaction and its final cost before signing. Donations are voluntary contributions, not investments or purchases of preferential treatment, promised results or priority support.
You control installation permissions, device security, wallet access and backups. Keep independent, verified backups and recovery material separately. Do not send secrets to support. MASTRpass cannot recover a lost master password or recovery key for you. Changing or uninstalling an app, losing a device or restoring a backup can affect locally stored data.
MASTRsweep and MASTRsender prepare actions for your wallet to authorise; verify recipients, networks, amounts, approvals and fees. Blockchain actions may be irreversible. Wallets, RPC providers, exchanges, app stores and linked sites operate under their own terms. Simulations, prices and chain observations reflect a moment in time and may change before execution.
Use the site and apps lawfully and only with data, wallets and systems you are authorised to use. Do not misuse them for fraud, unauthorised access or harm to others. Report reproducible security concerns privately to info@mastrapps.com without including real secrets or unnecessary personal data.
Software can contain defects and services can be interrupted. No tool, score, inspection result or publication guarantees protection from scams, malware, loss or every device compromise. No uninterrupted availability, future feature or platform release is promised. Keep a copy of the notices relevant to your release; material updates are dated. Nothing in these notices excludes rights or liability that applicable mandatory law does not permit to be excluded.

This static website has no user accounts, analytics cookies or tracking pixels. Language and display preferences may remain in your browser. The hosting provider may process IP addresses, request times, requested files, browser information and error/security logs to deliver and protect the website. No fixed retention period is asserted here without verified hosting settings; contact info@mastrapps.com for an applicable request.
MASTRpass Pro operates offline and has no network permission. MASTRsweep and MASTRsender need network access for wallet-related public data and transactions; RPC and wallet providers may observe addresses, requests and connection information. The separate $MASTR App uses accounts and messaging. Consult each app’s own notices; the website’s no-account statement does not cover every MASTR product.
If you contact info@mastrapps.com, the information you send is used to respond, investigate the issue and maintain necessary correspondence. Email and hosting providers may process it as part of delivery. Share only what is needed, redact unrelated personal data and never include private keys, seed phrases or recovery material.
Opening X, Telegram, Linktree, stores or explorers leaves this site and exposes the request to that provider. Direct APK downloads create ordinary hosting requests. Solana donations are public blockchain transactions; addresses, amounts and transaction history may be visible, and MASTR cannot erase the blockchain.
Contact info@mastrapps.com to request information about data you supplied, correction or deletion where applicable, or to raise a privacy concern. Information is retained only as needed for its purpose, legal obligations or relevant security records; those obligations may limit deletion. No promise of absolute confidentiality or system security is made.
