Effective date: September 15, 2026 · Applies to the Blanks Chrome extension (Chrome Web Store ID mhegkceocponjlnnbinngggdmniigkgo) and to the website trade-blanks.com. Data controller: the developer of Blanks (contact at the bottom of this page).
Summary. Blanks is a paper-trading simulator. By default it collects no personal data: your virtual wallet, trades and settings stay in your browser, and the only network requests are public price lookups that carry a token address and nothing about you. Three features are optional and opt-in — the Tracker (a pseudo you choose), Link with Google (a hashed Google id) and update emails (an email address) — and this policy explains exactly what each one collects, why, where it is stored, for how long, with whom it is shared, and how to delete it. We never sell data and never use it for advertising.
The extension saves the following in your browser's extension storage (chrome.storage.local, mirrored to chrome.storage.sync if you have Chrome sync enabled — in which case Google, not us, synchronises it between your own browsers under your Google account):
We have no access to this storage. It is deleted when you uninstall the extension, use "Reset wallet", or clear the extension's data.
On trade.padre.gg and axiom.trade, Blanks reads values already displayed on screen (token symbol, price, liquidity, market cap) to run the simulation and draws its own panel on the page. Nothing read from those pages is transmitted anywhere. Blanks never connects to a crypto wallet, never asks for a private key or seed phrase, and cannot perform real transactions.
To price tokens, the extension queries public market-data APIs: lite-api.jup.ag, api.dexscreener.com, and for the SOL/USD rate api.coinbase.com, api.binance.com, api.kraken.com, api.coingecko.com. These requests contain only a public token address. They carry no user identifier, no cookie and no account information. Like any web request, they expose your IP address to the service that answers; those services' own privacy policies apply to that.
Our server is trade-blanks.com/api. The extension contacts it only after you deliberately use one of the features below. Until then, no request is made to it.
| Feature (opt-in) | Data | Why |
|---|---|---|
| Tracker — Register a pseudo (Track tab) | The pseudo you choose (3–20 letters, digits or underscore); a random secret key generated on your device, stored on the server only as a SHA-256 hash. | To identify your pseudo so your simulated trades can be published under it and so you can manage or delete them. |
| Tracker — Sharing on | Your simulated trades: token address and symbol, side (buy/sell), amount in SOL, price and market cap, simulated result, timestamp. | To show them to the users who chose to follow your pseudo (as bubbles on their chart and in their feed). |
| Tracker — Following someone | The list of pseudos you follow (sent with each read request). | To return those users' published trades and profile photos. |
| Profile photo ("Add a photo") | The image you pick, cropped and shrunk to 64×64 pixels in your browser before upload (a few kilobytes). | To display it to your followers instead of your initial. |
| Link with Google / Recover with Google | A one-time Google sign-in token, verified with Google and then discarded; we keep only a SHA-256 hash of your Google account's technical identifier ("sub"). If you have no photo yet and accept it, your Google profile picture, shrunk to 64 pixels. We do not store your Google name, email address or the picture's URL. | To let you recover your pseudo, photo and published trades on another computer or after a reinstall, without an email or password. |
| Update emails (Settings → Updates, or the Changelog page) | Your email address, a random subscription token, whether you confirmed, and the last version we emailed you. | To send you one email per new version with the changelog, after you confirm from your inbox. |
Our server keeps no access logs. To limit abuse it holds the IP address of recent requests in memory for at most one minute; IP addresses are never written to disk or associated with an account. The website uses no analytics, no tracking pixels, no advertising and no third-party cookies.
We use the data listed in section 1.4 strictly to provide the feature you enabled: displaying your pseudo, photo and simulated trades to your followers; returning to you the trades of the pseudos you follow; recovering your pseudo through Google; sending you the changelog by email. We do not build profiles, do not use the data for advertising or marketing beyond the update emails you asked for, do not combine it with other sources, and do not make automated decisions with it. Simulated trades are exactly that — simulated; they involve no real funds and are not financial data about you.
We do not sell, rent or trade any data, and we do not share it with advertisers or data brokers. Data leaves our server only in these cases:
The public price APIs listed in section 1.3 receive token addresses only, never data about you.
Everything above is opt-in and reversible from inside the extension, immediately and without contacting us:
Under the GDPR and similar laws you also have the right to access, rectify, export or erase your data, to object to or restrict its processing, and to lodge a complaint with your data protection authority (in France, the CNIL). Write to the contact address below; we answer within 30 days. We do not knowingly collect data from children under 16; Blanks is not directed at them.
Features that send data to our server are processed on the basis of your consent (you enable them; you can withdraw consent at any time by deleting the account or unsubscribing) and, for keeping the service working and abuse-free, our legitimate interest in operating it.
If our practices change, we update this page, change the date at the top, and mention it in the extension's changelog before the change takes effect. Material changes that would collect new data will require your renewed opt-in.

Blanks est un simulateur : par défaut, il ne collecte aucune donnée personnelle. Votre wallet virtuel, vos trades et vos réglages restent dans votre navigateur, et les seules requêtes réseau sont des consultations de prix publiques qui ne contiennent qu'une adresse de token. Trois fonctions sont facultatives et sur activation explicite : le Tracker (un pseudo que vous choisissez, une clé secrète stockée hachée, vos trades simulés tant que « Sharing » est actif, une photo de profil de 64 px si vous en ajoutez une), le lien Google (un identifiant Google haché, jamais votre nom ni votre email) et les emails de nouvelle version (votre adresse, après confirmation depuis votre boîte mail). Ces données sont stockées sur un serveur hébergé par OVH en France, transmises en HTTPS, jamais vendues ni partagées avec des annonceurs ; les trades publiés s'effacent après 30 jours ; « Remove account », « Delete my published trades », « Remove photo » et « Unsubscribe » suppriment immédiatement ce qui vous concerne. Pour toute question ou demande d'accès, de rectification ou d'effacement : jneveu.work@gmail.com.
