Privacy Policy
SAF3 is designed with privacy at its core. We do not collect, store, or transmit any personal data.
1. Introduction
This Privacy Policy explains how SAF3 ("we", "our", or "the Extension") handles information when you use the SAF3 wallet Chrome extension. SAF3 is a self-custody cryptocurrency wallet built for the Abstract blockchain. By installing or using SAF3, you agree to the practices described in this policy.
2. Information We Collect
2.1 Personal Data
SAF3 does not collect any personally identifiable information (PII). We do not require account registration, email addresses, names, phone numbers, or any other personal identifiers to use the extension.
2.2 Wallet Data (Local Only)
The following data is generated and stored exclusively on your device using Chrome's built-in storage API:
- Seed phrases (mnemonic recovery phrases)
- Private keys
- Wallet addresses
- Encrypted vault data
- User preferences and settings
- Cached token balances and price data
All sensitive data (seed phrases, private keys) is encrypted using AES-256 encryption before being stored. Your password is held in memory only during your active session and is never written to disk.
2.3 Analytics & Tracking
SAF3 does not use any analytics services, tracking pixels, telemetry, crash reporters, or fingerprinting technology. We do not track your usage patterns, browsing behavior, or extension interactions.
3. Data Shared with Third Parties
SAF3 does not sell, rent, or share any user data with third parties. However, to provide core wallet functionality, the extension communicates with the following categories of external services:
| Service Type | Purpose | Data Sent |
|---|---|---|
| Blockchain RPCs | Submit transactions, query balances and contract state | Public wallet address, transaction data |
| Block Explorers | Fetch transaction history, verify contract data | Public wallet address |
| Price & Market APIs | Display token prices, market data, and trending tokens | Token contract addresses (no wallet data) |
| NFT Data Providers | Fetch NFT metadata, images, and collection info | Public wallet address, token IDs |
| IPFS Gateways | Resolve decentralized content (token logos, NFT media) | Content identifiers (CIDs) |
All communication uses HTTPS. Only publicly available blockchain data (your public wallet address) is included in these requests. No private keys, seed phrases, passwords, or personal information are ever transmitted.
4. Chrome Extension Permissions
SAF3 requests the following browser permissions and uses them strictly as described:
| Permission | Purpose |
|---|---|
storage |
Store your encrypted wallet vault, cached balances, and user preferences locally on your device |
alarms |
Schedule background price and balance refresh intervals |
notifications |
Display transaction confirmation alerts |
sidePanel |
Provide an optional browser sidebar view |
| Host permissions | Communicate with blockchain RPCs, block explorers, price APIs, and NFT data sources listed in Section 3 |
| Content scripts | Inject the Web3 wallet provider into web pages so dApps can request wallet interactions. The content script does not read, collect, or modify page content |
5. Data Storage & Security
- Encryption: All sensitive wallet data is encrypted with AES-256 before being written to Chrome's local storage.
- Password handling: Your wallet password exists only in volatile memory during an active session. It is never persisted to disk or transmitted externally.
- No remote storage: SAF3 does not operate any servers or databases. There is no cloud backup, no remote sync, and no server-side component.
- Local-only architecture: All wallet logic runs entirely within the Chrome extension sandbox on your device.
6. Data Retention & Deletion
Because all data is stored locally on your device:
- Uninstalling the SAF3 extension removes all locally stored wallet data, preferences, and cached information from your browser.
- Clearing extension data via Chrome's settings will also remove all SAF3 data.
- We retain no data on any server — there is nothing for us to delete on our end.
7. Children's Privacy
SAF3 is not directed at individuals under the age of 18. We do not knowingly collect information from children. If you are under 18, please do not use this extension.
8. International Users
SAF3 does not transfer personal data internationally because we do not collect personal data. The third-party API requests described in Section 3 are initiated from your device directly and are governed by those services' own privacy policies.
9. Your Rights
Because SAF3 does not collect or store personal data on any server, traditional data-subject rights (access, correction, deletion, portability) are satisfied by default. You have full control over all data stored locally on your device. You can view, export, or delete your data at any time through the extension's settings or by uninstalling.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected on this page with an updated "Last modified" date. Continued use of SAF3 after changes constitutes acceptance of the revised policy.
