The report

Balance, value, and how it got there.

This is a static example. Look up an address or open the public example to see live data.

01 · Chain notes

What the chain shows, not a safety rating.

Notes describe things the chain shows: output count, repeated use of an address, and small outputs. They are not a verdict that an address is safe, and they are not an instruction to move funds.

02 · Confirmed transfers

Market value on the confirmation date.

Confirmed transfers in the report can show an estimated market value using daily prices. That is not every transfer ever, the price someone paid, a sale, or a taxable gain.

03 · Collectibles

Inscriptions and runes.

This example includes 24 inscriptions and 3 runes, from PNGs to HTML and 3D.

04 · Saved addresses

An optional account saves up to three addresses.

Lookup needs no account. A free Watch account can save up to three addresses and your display preferences.

Bitcoin network

Follow the Bitcoin network.

Every watch includes a live Bitcoin market and network dashboard.

Privacy

Last updated: September 26, 2026

You can look up Bitcoin addresses without an account. Creating an account requires no email or identity documents. We do not use lookup activity to build advertising profiles or provide lookup queries to advertisers.

Your account

We store your username, saved addresses, names, private notes, colors, preferences and paid access to provide your account features. Private notes do not appear in public address reports. Signed-in History downloads include your saved transaction notes (Ledger Notes); private address-card notes are not included.

Passwords and Watch Keys are stored as hashes and checked when you sign in. Session and security records may include hashed network and browser information.

Lookups and service providers

We use request logs to operate and protect the service. They can include the addresses and pages requested, request details, timestamps and browser information. Our web logs mask part of your IP address; our Bitcoin-data API logs remove it for satoshis.watch requests. These records are not fully anonymous.

Cloudflare processes requests to deliver and protect the site. If our own history source is unavailable, we may send the requested Bitcoin address and transaction IDs to mempool.space. Each provider handles that information under its own privacy policy.

In your browser

Cookies keep you signed in, and browser storage remembers display preferences. Our page counter uses no cookies or stored identifiers. You can clear site data in your browser. Privacy mode hides information on screen; it does not change network requests or logging.

Payments and messages

Payment records connect your account with the method, amount, status, dates, invoice or address, and transaction details. USDC recovery may also record a payer address. Checkout asks for no name, email, mailing address or card number. Payment networks and providers maintain their own records.

If you contact us, we store your message, optional email, the originating page and site, time and masked network information to handle your request.

How long records stay

Web request logs normally cover about four days; Bitcoin-data API logs cover about a year. Network and browser hashes in account audit records are scheduled for removal after 72 hours. Sign-in sessions normally last 30 days and may be renewed by use.

Deleting your account ends access and clears private notes from the live account. Some account, security, payment, message and backup records remain; the log periods above do not apply to those records. Clearing browser data removes the browser's copy only.

Your choices and questions

You can edit your saved information or delete your account in account settings. For access, correction or deletion requests, or questions about this policy, contact us. We date updates on this page. Our Terms of use also apply.

Terms of use

Last updated: September 23, 2026

These terms cover your use of satoshis.watch, part of the satoshidata.ai ecosystem. By using the service, you agree to them.

Using satoshis.watch

We help you explore the public Bitcoin blockchain, follow addresses and understand their history. We do not hold your bitcoin, control your addresses or ask for private keys.

Balances and transactions come from blockchain records. Labels and estimates add context and may be incorrect or outdated. Reports are for information, not financial, investment, tax, legal or compliance advice. You are responsible for your decisions; check information independently before acting on it.

Your account

Your account saves addresses, private notes and preferences. Keep your password and Watch Key secure, and only give access to people or tools you trust. You can delete your account at any time. Our Privacy page explains how we handle account data.

Paid features

Prices, included features and access periods are shown before payment. Available payment methods are listed at checkout. Small digital payments are generally non-refundable, except where the law requires otherwise. If a payment or activation goes wrong, contact us.

Fair use

Use the service lawfully and respect others' privacy. Do not disrupt it, bypass access or rate limits, run unauthorized security scans, or use its data to expose private identities, harass or endanger anyone. Do not present an uncertain label as proof or as our endorsement of an accusation.

We may limit or suspend access to protect the service or address misuse.

Data and ownership

Public blockchain data and public facts remain public. Our original software, design and compiled analysis are protected by their applicable rights and licences. You may not repackage or resell our compiled datasets or analytics without permission. Existing open-source licences continue to apply.

Availability and responsibility

The service is provided "as is" and "as available," without warranties of accuracy, completeness, suitability or uninterrupted access. To the extent permitted by law, we are not liable for losses arising from using the service, being unable to use it, or decisions based on its data. Nothing in these terms limits rights or liabilities that cannot legally be excluded.

Updates and questions

We post changes here with an updated date. Continuing to use the service after a change takes effect means accepting the revised terms. For questions about these terms, contact us.
