Privacy Policy

Last updated October 9, 2026

This policy explains what information Line Tappy ("LineTappy", "we") collects, how we use it, and your choices. It covers the LineTappy app, this website and our support channels.

What LineTappy stores

• Your account: your email address and sign-in details, handled by Google Firebase Authentication. We never see your password.
• Your Twilio connection: your Twilio Account SID and the API key LineTappy uses, encrypted with keys held in hardware security modules. If you connect with your Auth Token, it's used once to create that key and is never stored.
• Your choices: which of your numbers LineTappy uses, your block list (including which numbers you reported as spam), and how each number's calls and texts are handled, including a copy of the Twilio settings we changed so we can put them back.
• Which conversations you've read or archived: for each conversation, the two phone numbers, how far you've read and whether you archived it, so the app and the web app agree. Never the texts themselves.
• What you agreed to: which version of these terms you accepted and when, and that you confirmed you're 18 or older.
• Your voicemail greetings: the words you type for a number's greeting, and any greeting you record. Recordings are kept privately in encrypted storage; Twilio plays one to a caller through a link that expires after a few minutes. They're deleted when you replace them, disconnect Twilio or delete your account.
• Your devices: a notification token for each phone and browser you sign in on, with its name (such as "Pixel 9" or "Chrome on Windows"), so we can tell it a new text or call has arrived.
• Subscription status, from Google Play or our payment processor. We don't see or store full card numbers.
• Support chats, if you use the chat on our website: kept for 30 days so our team can follow up, then deleted (see below).
• Crash reports: when the app or the web app runs into an error, a report of what went wrong and where in LineTappy's code, with your device or browser type and the app version. Phone numbers and email addresses are removed first, and no message text, contacts or account details are included. The app's reports go to Google Firebase Crashlytics, which keeps them for 90 days; the web app's go to our own logs, kept for 30 days.

What LineTappy doesn't store

Your texts, photos and call recordings stay in your own Twilio account. LineTappy passes them to your phone when you use the app, and keeps a copy only on your phone, and in your browser if you use the web app (signing out of the web app deletes it). Notifications we send carry an ID, not the message.

How we use information

Only to provide LineTappy: signing you in, connecting to your Twilio account, delivering your texts and calls, notifying your phone, billing, keeping the service secure, and answering support requests. We don't sell your information, and we don't use it for advertising.

Your texts and phone numbers

LineTappy doesn't send text messages to you itself; support is by email, or the chat on our website. The texts you send and receive with LineTappy go through your own Twilio account; LineTappy passes them along without keeping them.

No mobile information, including phone numbers and the content of texts, is shared with third parties or affiliates for marketing or promotional purposes.

Support chat

The support chat on our website is answered by an AI assistant, provided by Anthropic. When you use it, your messages, the assistant's replies, and basic facts about your LineTappy account (your plan, whether Twilio is connected, which numbers you use and whether they're registered for texting) are sent to Anthropic to produce the replies. Anything that looks like a password, Auth Token or card number is removed first. Anthropic processes chats on our behalf and doesn't use them to train its models.

A chat is emailed to our support team when you ask for a person, when it reaches its length limit, or when the assistant reports a problem, so we can reply to you by email. Chats are deleted after 30 days, or when you delete your account.

You can also use the chat without signing in, for general questions. Before it starts, Cloudflare Turnstile checks that you're a person and not an automated program; Cloudflare sees your browser and internet address to do that. We then keep only a one-way hash of your internet address (it can't be turned back into the address) to limit how often the chat can be used, with that chat's messages, for 30 days. These chats aren't linked to any LineTappy account and aren't emailed to our team; for more help, you email us yourself.

Service providers

We use Microsoft Azure (hosting, encrypted storage and support emails), Google Firebase (sign-in, notifications and crash reports), Google reCAPTCHA (a check that sign-ups and sign-ins aren't automated), Anthropic (the support chat's AI assistant), Cloudflare (the support chat's check for automated programs), Twilio (your own account, which you connect) and, for subscriptions, Google Play and our payment processor. Each handles data under its own privacy terms and only as needed to provide LineTappy.

Security

Credentials are encrypted and can only be decrypted by the LineTappy service, never by staff in the normal course of business. Connections are encrypted in transit. Logs are filtered so they never contain credentials.

Your choices

• Disconnect your Twilio account at any time in the app's Settings; we forget its key and restore your numbers' original Twilio settings.
• Delete your account yourself, in the app or at app.linetappy.com, or delete just some of your data. See Delete your account for how, and what's deleted.
• Ask what we hold about you, or to correct it, at the same address.

Children

LineTappy is only for people 18 or older. We don't knowingly collect information from anyone under 18; if we learn we have, we delete it.

Changes

If we change this policy, we'll update the date above, and tell you in the app for significant changes.
