Privacy policy. We never give out your info for any reason whatsoever, unless a) where it makes sense during booking or b) it is required by federal or state law.


There are two types of Hummingbook users: providers and clients.

Providers are users who provide services to clients.

Clients are users who consume services from providers.

E.g. Carlita is a hairstylist. She’s a provider. Carlita pays Hummingbook a monthly fee to make her life easier and book clients. Haley is a client with split ends. Haley pays Carlita to cut her hair.


This section is for our providers. ”You” and ”your“ refer to you, the provider, in this section. “We” refers to Hummingbook the company, the application, and the website.

Your appointments

Your clients never see appointments you have scheduled with other clients, only your availability. We never give your appointment info out to anyone. Our team might see your appointments, but only for setup, improvement, testing, etc.

Your name, email address, phone number, and business address

Your name, email address, phone number, and business address will only be shared with your clients when they book with you. (That’s a good thing.)

Everyone else in the world sees nothing. We never give, sell, or hand out your info—your name, email address, phone number, and business address—to anyone. The thought of such a thing is simply repulsive to us. It. Never. Will. Happen. (Unless required by law).

We might email you about product improvements or if we have exciting news. You can easily unsubscribe at any time.

Your clients

Your clients are yours. Not ours or anyone else’s. We’ll never sell or hand out their information. (Our team might see your clients’ info, but only for support, improvement, or testing.)

Your clients will receive confirmation and notification messages regarding their appointment, otherwise we wouldn’t be terribly useful.

We might ask your clients here and there how they felt about our service so we can improve it for you (and them).

Your Google calendars

By using Hummingbook, you’re granting Hummingbook access to the calendar portion of your Google account.

Hummingbook creates two new, Google calendars called Appointments and Availability.

Hummingbook uses these two calendars to store your availability and your appointments. (If it didn’t, Hummingbook wouldn’t be very useful to you as an online booking system!)

Technically, Hummingbook can access (read, write, delete) all your Google calendars & events. However, in practice, Hummingbook only reads/writes events to the two aforementioned calendars (unless you specifically instruct us to connect to a different calendar.)

In general, Hummingbook does’t muck with (aka: read/write/delete) your other calendars.

Hummingbook also automatically shares your Appointments and Availability calendars with a member of our support team. (e.g. This is so we can quickly help you if needed, for product improvement, testing, and tuning on your account. You can change access levels to these calendars or revoke access at anytime via your Google Calendar settings.

You can also revoke Hummingbook’s access to your Google Calendar account entirely with one click.

Your Google account

We can’t access other portions of your Google account. Your Google Gmail, Google Contacts, Google Drive, and anything else in your Google account is off limits to us. We only have access to your Google Calendar.

And of course, your Google password is never shared with us.

See Google’s privacy policy for their rules regarding your info.

Our Servers

When you’re on our website everything is encrypted and secured. That means nobody can intercept your email address or password or any other account info. Look for the padlock in your browser’s title bar for the warm fuzzies.

Your password

We never see or know your password. In fact, we can’t recover your password even if we tried. It gets totally encrypted. That’s why if you forget it, we’ll have to have you reset it—because we don’t know it. (It’s a mishmash of numbers and letters on our end.)

Your credit card (providers and clients)

We use a rock-solid, industry-leading company called Stripe to handle and store all your sensitive cc info. Your card’s details are never stored on our servers (or on our providers’ servers). In fact, your credit card is so secure, we don’t even know the full number. Neither do our providers.

Translation: if we, or your provider, wanted to buy a fresh pair of Nikes on your dime, we/they couldn’t. Because we/they don’t have your actual card info on file. We/they have a representation of your card info, which is meaningless to any retailer. Here’s a card number: card_1GIjDtEusNwdymuvakZ8xcRU. Last four? 4242. Try to use it somewhere. You can’t.

We use Stripe to collect credit card info without it ever being stored on our servers. Here is Stripe’s privacy policy if you’re interested.


This section is for clients. (See definitions at the top of this document). ”You” and ”your“ refer to you, the client, in this section. “We” refers to Hummingbook the company, the application, and the website.

Your credit card (clients)

If you, the client, perform a transaction with a provider via Hummingbook, your credit card, while obfuscated as explained above (provider’s section), will be stored in the provider’s Stripe account. Your provider has the power to charge your card for services/products/late-fees/no-shows/etc. We expect providers to be ethical. However, we are not in control of their policies or actions. Any and all transactions and/or disputes are between you and your provider. See our terms of service for more info.

Your personal info: name, email, phone, etc. (clients)

When you book an appointment, we share your name, email, phone, and other pertinent info with the provider. If we didn’t, we wouldn’t be terribly useful as a booking system.

We will never share or sell your info with anyone other than your provider(s) who you booked with on Hummingbook. We’re NOT in the business of selling people’s personal info. If for some godforsaken reason we decide to get into that business, we would first obtain written consent from you to share your info.

Your provider(s) might keep an email or phone list and send you promo info, specials, announcements, etc. While we hope they are ethical with your info and will never give it out or sell it, we can’t make any promises on their behalf. Thus, only book with providers you trust.
