Privacy
A shared fire with a deliberately small data footprint.
Anonymous Ember identity
A random browser identifier is stored in first-party local storage. On your first accepted burn, the service stores that identifier with a sequential Ember number and first-burn time. This prevents ordinary reloads from creating another Ember. No fingerprinting, name, email, account or wallet address is attached. A different browser or cleared site storage can still create another Ember, so the total is not a verified count of people. Ember records are retained while the shared identity feature operates.
Daily activity
The same anonymous identifier prevents more than one counted burn per UTC day. Daily deduplication records are kept for up to 35 days; daily and hourly aggregate totals may be retained for historical product measurement. Visual burns remain available even when a repeat is not counted.
Connections and aggregate measurement
The page connects directly to public Bitcoin data providers including Kraken, Coinbase, mempool.space and Blockstream. Those services receive ordinary connection information under their own policies. Cloudflare serves the site, processes security and rate-limit signals, and may provide aggregate traffic analytics. Product events such as share intent or address copy are stored only as daily aggregate counts; the event table does not store the browser identifier.
Sharing and story cards
Sharing happens only after you choose an action. A spark URL contains only an Ember number and is not a security credential. X and native sharing open the service you select. Story cards are rendered in your browser. The site records an aggregate intent when a sharing control is used, not proof that a post was published.
Contact
The contact form sends the name you choose to provide, your reply email and message to the creator through Cloudflare Email Service. The destination address is not exposed in the page. Contact details are used to read and reply to that message and are subject to normal email retention. Rate limiting processes connection information to reduce spam.
Bitcoin tips
The tip panel displays the creator’s ordinary Bitcoin address and copies it only when you choose the copy control. There is no wallet connection, payment gateway or invoice service. Transfers happen in your own wallet. Bitcoin transactions, including addresses and amounts, are public on the blockchain; this site does not match transfers to visitors or confirm payments.
