Public wallet data.
Persistent scan summaries.

Product data policy for MASTRflex, operated under MASTRlabs at mastrlabs.com/MASTRflex. Updated September 19, 2026. Contact: mastr@mastrlabs.com. The main website’s legal operator information also applies.

Scanning

Scanning stores a public activity summary without an expiry date. A new scan updates the same wallet entry. Only temporary raw transactions are deleted after 1 hour.

Publishing and deletion

The board shows the beginning and end of each address. This is shortened display, not anonymity: addresses are available in API responses and rescan links. Signing a public page is optional.

A verified owner or the operator can remove an entry. Removed wallets are not automatically re-added by another scan. Copies on other services cannot be recalled.

Public pages and leaderboard summaries have no automatic expiry. Hosting data must remain intact. Storage limits still apply; reaching capacity does not erase older entries.

Cookies, receipts and protection against abuse

An essential HTTP-only, same-site session cookie associates scans and signed-message challenges with the current browser session. Payment receipt references may be stored in your browser. With your explicit opt-in, up to 8 wallet addresses and 8 activity summaries per wallet are saved on this device for sample comparisons. This is not a lifetime activity log. You can forget a wallet or clear this storage; no background scans or notifications are enabled. Application request limits use a keyed hash of the connecting IP address. These rate-limit entries expire within their configured time window, normally no more than 1 day; cleanup is traffic-triggered. This is pseudonymisation, not anonymity. The package contains no advertising trackers or analytics SDKs.

Local collection and Android exports

Collection cards are saved only on this device, up to 200 entries. They are not NFTs or ownership certificates. Browser data clearing or uninstalling the Android app may delete them. The collection can be cleared without removing the public leaderboard.

The Android alpha opens the hosted website inside a WebView. Signing is not performed by a native wallet bridge in this build. An explicit action opens a compatible external wallet browser. PNG, CSV and JSON exports require Android confirmation before being saved to Downloads/MASTRflex and offered to an installed sharing app. Files may include wallet activity. No private keys are received. The APK contains no RPC credentials or advertising SDKs.

Limitations and leaderboard rules

Reports use an address-history sample, not guaranteed lifetime history. Token-account-only transactions can be missing. Local FIFO PnL is an estimate only for supported, unambiguous spot swaps with observed acquisition cost. Fees are separate; SOL and USDC are never added without conversion. Unsupported trades, perps, NFTs and unobserved acquisition cost are not assigned fictional profits. Losses do not establish a rug.

Entries stay until explicitly removed. A new scan updates the same wallet. Use All wallets and the page controls to browse the complete board. Rankings use the latest stored sample, not lifetime totals. The last scan date and observed period stay visible.

Titles, balance and self-declared memes

Whale and Rich Bitch titles describe thresholds of native SOL recorded at scan time, not a person’s wealth, total portfolio value, profitability or investment ability. Older summaries without a balance observation do not receive balance-based titles until a new scan. UTC activity titles use UTC, not the owner’s local time.

Creative titles and roasts are in English; interface controls retain the existing language options. Custom stickers are decorative graphics, not tokens, NFTs, security badges or financial rewards. There are 48 illustrated motifs with 64 frame-and-seal variants per motif.

Rug Victim and related self-roasts are optional self-declarations, not automatic findings. Publishing a self-declaration requires an expiring, exact-message wallet ownership signature. The selected declaration and graphical variation are bound into that message. No failed-transaction count is presented as a rug count.

Payment

Standard card export and sharing are free. When the operator configures a receiving wallet, additional local Studio export options may be offered for an explicitly displayed one-time SOL fee plus the network fee. No purchase is possible before recipient configuration. The checkout shows the receiving address and exact amount, simulates the transaction, requests explicit wallet approval and checks finality and payment instructions. Network transactions are generally irreversible; contact the operator with the transaction signature concerning any delivery problem. No seed phrase, private key, token approval or discretionary trading authorization is requested. The local Studio UI is not tamper-proof licensing, and the software does not represent it as such.

Receipt Market and supporter ranks

The Receipt Market is disabled until the operator configures a valid Solana receiving wallet. Primary-store purchases transfer the displayed SOL price directly to that receiving wallet. Peer-market purchases transfer the seller payout directly to the seller wallet and the displayed platform fee directly to the configured MASTR treasury in the same buyer-approved transaction. MASTRflex does not take custody of seller proceeds.

Seller listings and cancellations use exact message signatures. A message signature does not move SOL or tokens. Purchases use a plain SOL transaction containing only the displayed transfer or transfers plus a MASTRflex memo. The server verifies payer, recipients, amounts, instruction count, memo, wallet signature and finality before assigning the purchased collectible.

Server-issued MASTRflex collectibles are wallet-linked digital items inside this product. They are not onchain NFTs until a separate onchain mint system is actually deployed. Transferable items may be listed in the peer market. Supporter ranks are wallet-bound cosmetic badges and never change Hall position, Arena results, wallet metrics or trading reputation. No resale value or profit is promised.

Third-party links and acceptable use

Choosing X, Telegram, WhatsApp, Bluesky, LinkedIn, Facebook, another native sharing app, a wallet provider or Solana Explorer sends you to that service, whose own terms and privacy policy apply. Do not publish misleading names, impersonate identities, upload fabricated financial claims or use this service to harass others. The operator may remove abusive entries. Questions or removal problems can be sent to the contact above with the public report link; never send wallet secrets.
