Your practice.
Your local ledger.

1. What PaperFills reads

On axiom.trade, PaperFills reads the current route and public token or pair identifiers, visible market information, trading controls, selected amounts, presets, fee settings, hotkey configuration, and relevant wallet and portfolio interface content. It uses this information to recognize paper-trade actions and show simulated balances, positions, orders, chart markers, and PnL. It does not request Chrome browsing-history access or inspect unrelated websites.

Paper markers, order levels, and active-position totals are shared with the chart inside Axiom's page context. Axiom's page scripts can observe these displayed paper values and page-world messages. Axiom independently processes your website login, cookies, wallet connections, and any real trades; its data practices are separate.

2. What stays on your device

Chrome's extension-local storage holds simulation settings, paper balances, holdings, fills and timestamps, pending orders, funding adjustments, and cached Axiom presets, hotkeys, and display preferences. Solana and Robinhood Chain paper wallets have separate local wallet books containing Axiom wallet names and displayed public-address identifiers. PaperFills also reads public-address attributes on Axiom's Wallets page to match rows. It does not request private keys or Chrome clipboard-read access. It does not use Chrome storage sync to upload the ledger. JSON export creates a local file only when you request it; import reads the backup you select.

Extension-local data is not separately encrypted by PaperFills. Anyone with access to your browser profile or exported backup may be able to read it. Use your operating system's account and disk protections, and do not put credentials or real wallet secrets in backups.

3. Market-data requests

PaperFills sends HTTPS GET requests to api.dexscreener.com containing a supported chain and public token or pair address needed for a quote, including a wrapped-native token address for an independent SOL/USD or ETH/USD lookup when needed. Requests omit browser credentials and do not attach paper balances, trades, wallet identifiers, wallet keys, or backups. DexScreener receives ordinary connection information such as your IP address and request timing and may log it under its own practices. Pending paper orders can cause quote lookups while Chrome is running even when the trading tab is closed. A displayed market price is not a guaranteed executable fill.

Opening this hosted policy lets its hosting provider receive normal web-request information such as your IP address and request time. This policy page has no analytics, advertising scripts, forms, or third-party embeds.

4. Diagnostics and limited use

The troubleshooting profiler is off by default. When explicitly started, it temporarily measures action types, selected-wallet counts, timing, frame gaps, long tasks, and coarse page-memory use. It does not collect wallet identifiers, balances, token identifiers, or trade amounts. Reports are displayed or downloaded only on request, not uploaded to PaperFills or saved in the paper ledger. A report displayed in Axiom's page may be visible to Axiom's scripts; reloading clears the in-memory report.

The extension has no advertising, analytics beacon, data-sale feature, or developer-operated data-collection endpoint. The developer does not receive your local ledger through the extension. Data is used for the paper-trading features described here, not advertising, unrelated profiling, credit decisions, or lending. PaperFills does not sell user data. Public token and pair identifiers go to DexScreener only for market-data features. A support message or backup you choose to send is a separate disclosure you control.

5. Retention and deletion

Data persists across normal browser restarts in this installed extension's Chrome profile. Paper history retains up to 2,000 recent fills and 100 recent funding events per wallet ledger; older detail may be trimmed while aggregate balances and recorded transaction counts remain. New fills retain position-lifecycle identifiers and cumulative totals. Older data may lack these totals and is not reconstructed.

A confirmed reset clears paper-wallet ledgers on the selected chain, not another chain, cached preferences, or all legacy data. Uninstalling the extension removes its extension-local data. Exported JSON files are not removed by reset or uninstall; delete them yourself if no longer needed. Switching paper mode off stops new scheduled paper fills but restores Axiom's native live controls. To stop extension activity, close Axiom tabs and disable or uninstall PaperFills.

6. Permissions

Storage saves local settings and paper ledgers. Alarms schedules pending-paper-order checks while Chrome runs. Site access is limited to axiom.trade and api.dexscreener.com for public quotes. PaperFills does not request access to all websites, global browsing history, camera, or microphone.

7. Contact and updates

For privacy or support questions, email paperfills1@gmail.com. Product updates are at @paperfills on X.

If you email support, your email provider and the developer receive the address and message you send, including attachments. Do not send wallet secrets, passwords, authentication cookies, or unredacted ledger backups. Changes to extension data handling will be reflected in an updated policy and, where required, a new disclosure or consent request.
