About BitcoinTipJar
BitcoinTipJar turns your Lightning address into a tip page, a QR code and a poster. When someone tips you, their wallet pays your wallet directly. We make the page and the QR code, and we're never in the middle of a payment: we never hold your money and never take a cut.
"Paid ✓" and tipper names
The "Paid ✓" a tipper sees comes from your own wallet, through a Lightning standard called LUD-21. A tipper's name travels with the payment the same way, through LUD-12. Wallets that support these show them, and every wallet still receives the tip. See which wallets do what.
At an event with a live tip wall, a tip to a speaker's jar shows on the event's big screen while the event is on, with the first word of the name you typed. The jar's page says so under the name field: leave the name empty to tip quietly.
What we keep
If you claim a short link, like bitcointipjar.com/yourname:
- your Lightning address, which is where that link sends your tips;
- your jar's settings, and your email, where we send your edit link and tell you if your payout address or email changes;
- a record of the tips your wallet confirmed, which you can delete.
If you connect an app to your jar, that app sees the tips your jar receives: the amount, the time and the name the tipper typed. Disconnect it on your edit page and it stops.
A jar someone else made for you holds your email only to send the setup link and up to two reminders. The link in every email removes it. A jar made with no email on file can be switched on by whoever scans it, unless it came from the Orange Wave: those switch on only from the card handed to the venue. We don't check that they own it, and the person who made it can report a wrong claim to abuse@bitcointipjar.com.
If you order printed stands, we keep the name, postal address and email you order them with: the address to post them to, and the email to tell you they're on the way and then in the post. A logo you add for them is kept to print it, and the file you sent is deleted 90 days after they're posted. An event kit keeps the same, and the event's name and dates, a sponsor's name if you give one, and the stalls' prices and the ticket link if you add them. The names, Lightning addresses and emails on its list make an ordinary jar for each person, kept as any jar is.
If you buy a power-up for a tip, we keep the name and message you give it, to show on the jar, on the owner's stream or on an event's big screen, and a salted hash of your IP, so the jar's owner can block it. The hash can't be turned back into you. If you buy Read aloud, Google's Text-to-Speech turns your name and message into the recording, and we delete the recording after 7 days.
If you join the Orange Wave, we keep your Lightning address, where your sats go; your email, where your dashboard link goes; the name you give; your country; the places you bring on; and what we pay you.
If you get a developer key, we keep your email, the company and the lines you give us, a fingerprint of the key but never the key itself, how many calls it makes each day, a salted hash of your IP, which jars have connected your app, and what we pay you as a partner. We use the email to confirm it's you, to send a new-key link when you ask, to tell you about your webhook and your share, and to write to you about building it into your app. The wallet check keeps the wallet's domain, never the address you checked.
If we've written to you and you reply, by email or on Nostr, we keep your reply with the contact details we found for you, so we can answer it and stop writing when you say no. Email replies reach us through our mail service, Brevo, and replies are sorted automatically. Reply with the word unsubscribe and we won't write again.
The map page at /map uses Google Maps, and so does the Map tab on a jar's edit page once you open that tab, and the place search on an Orange Wave dashboard. When you do, Google sees the same things any website using its maps sees: your IP address and what you looked at or searched for. The only other thing this site loads from elsewhere is the pay card from theorangebutton.com, and only when you choose to pay us in bitcoin, for printed stands, a power-up, an event kit or a venue plan; that card loads its fonts from Google, so Google sees your IP address then too. A nomination stores a hashed key from your browser and a hashed IP, both salted, so we can count two nominations a week; neither can be turned back into you.
What a tip jar can't show
Nothing illegal, no posing as someone you're not, and no scams, phishing or malware. To report a jar, email abuse@bitcointipjar.com with its link, and we'll take it down if it breaks these rules.
