Privacy Policy

Last updated 24 October 2026

This policy explains what LineTack (“LineTack”, “we”) collects, why, and what we do with it. LineTack is operated by BYTEDev Inc., a Delaware corporation in the United States.

1. Who this covers

LineTack is sold to businesses. Two kinds of people appear in this policy: the subscribing business and its office staff, who hold accounts with us; and the business’s workers, who are enrolled by their employer and who send text messages to the business’s LineTack number. We also process information about the business’s own customers, as it appears in the business’s accounting records and on receipts. This policy also covers visitors to linetack.com, including anyone who uses our calculator.

2. What we collect

• Account information — the name and email address of the people who administer the account, and a signed, HTTP-only session cookie once they sign in.
• How you found us — if the link you used to reach the app carries a referral code or campaign tags (the ref, utm_source, utm_medium and utm_campaign values), we hold those values in a short-lived, HTTP-only cookie for up to 30 days and, if an account is created in that time, record them on the account so we know which referral or campaign brought it. The cookie holds nothing else and is used for nothing else.
• Calculator requests — if you use the missed-billables calculator on linetack.com and ask us to email you the breakdown, we keep what you typed: your name, email address and shop name, your phone number if you gave one, your trade and the four numbers you entered, the estimate we calculate from them and the figures the page showed you, the date and time, any referral or campaign tags on the link you came from, and the version of the consent text you saw. We also keep the network address the request came from, to limit repeat requests, and a note of whether the breakdown email and our internal alert were sent.
• Language choice — if you pick a language on linetack.com or in the app, a cookie named lt_lang remembers it for one year. It is shared between linetack.com and app.linetack.com, holds only a language code, and is used for nothing else.
• Messages sent to a LineTack number — the message text, the sending phone number, the time it was received and, from a listed worker who has replied YES, any photo in the message. Before we store a photo we shrink it and remove the location and camera data the phone attached. We keep it in a private storage bucket, show it only to that business’s own users, and read it to pull out the receipt lines, store, date and total. A photo that is not a receipt is stored and shown the same way, so the office can see what was sent. Photos from numbers that are not listed, have not replied YES, or have opted out are never stored; our messaging provider receives every photo as part of carrying the message. Receipts sometimes show the last digits of a card or a signature; we do not use them for anything, and they go when the photo goes.
• QuickBooks Online data — when a business connects its QuickBooks Online company, we read the records needed to match a charge to the right customer and job: customers, sub-customers and jobs, items, vendors, and account preferences. We write the charges the business approves.
• Service records — what was parsed, what was approved, edited or rejected, by whom and when, and the request and response of each write we make to QuickBooks Online.
• Technical logs — errors and diagnostic identifiers needed to operate the service.
• Website visits — linetack.com uses Cloudflare Web Analytics, which counts page views without cookies, local storage or fingerprinting. Cloudflare receives the page address, the referring page, your browser type and your IP address to produce aggregate statistics; we see only those aggregates.

We do not ask for, and the service does not need, bank credentials, social security numbers, or health information. If you choose a paid plan, your card is collected and stored by our payment processor, Stripe; LineTack never sees or stores your full card number. We keep the plan, amounts and dates you agreed to, and the payment status Stripe reports to us.

3. Why we use it

• To read a message or receipt, match it to a job, and prepare a draft line for review.
• To show that draft to the business and record the approval decision.
• To write approved charges to the business’s connected QuickBooks Online company.
• To keep a record of how each line was produced, so the business can audit it.
• To email you a calculator breakdown you asked for, and to follow up on it as the form says.
• To support, secure, debug and improve the service, and to meet legal obligations.

We do not use message content or QuickBooks data for advertising, and we do not sell personal information.

4. Text messages and consent

Workers are enrolled by their employer, who is responsible for obtaining their consent before adding them and for recording it. A worker may stop messages at any time by replying STOP, and HELP returns help information. Message frequency varies with use, standard message and data rates may apply, and carriers are not liable for delayed or undelivered messages.

Your mobile information will not be sold or shared with third parties for promotional or marketing purposes. We do not share mobile opt-in information, phone numbers, or consent records with third parties or affiliates for their own marketing purposes. Phone numbers are shared only with the messaging provider that carries the message on our behalf, for the purpose of delivering the service.

5. Who we share it with

We share information only with service providers who process it on our instructions, and only as needed to run the service:

• Intuit — to read from and write to the QuickBooks Online company the business connected.
• Our messaging provider — to receive and send text messages.
• Our email delivery provider — to send sign-in, account and billing emails, and the emails that deliver approved lines as a CSV, to the people who administer the account; and, if you ask our calculator for a breakdown, to send that email to you and an alert to us. It receives their name and email address and the content of those emails. For the CSV emails, that content is the business’s approved lines: job names, descriptions, quantities, unit costs, markup, prices, approval times and a LineTack reference code. For the calculator emails, it is your email address, the figures in the breakdown and, in the alert to us, what you typed into the form.
• Stripe — to take and store card payments for paid plans. Your name, email and card details go to Stripe directly (stripe.com/privacy).
• Our hosting and infrastructure providers, including Cloudflare — to run the service and the website, to store what we hold, including receipt photos, which sit in a private storage bucket, and to produce the aggregate website statistics described in section 2.
• The AI model provider that reads your messages — the text of each message, and any stored photo, is sent to a third-party model provider to extract the line items and, from a receipt, the store, date and total. This is how the reading is done. The provider processes it on our instructions, under terms that prohibit training on it.

We may also disclose information if required by law, or in connection with a merger or sale of assets, in which case we will give notice before information becomes subject to a different policy.

6. How we protect it

• Access tokens for QuickBooks Online are stored encrypted, and are never written to logs.
• Credentials and secrets are held outside application code, with file-level access restrictions.
• Access to production data is limited to people who need it to operate or support the service.
• Each business’s data is kept logically separated; we do not combine one customer’s data with another’s.
• Data is encrypted in transit.

No system is perfectly secure, and we do not claim otherwise.

7. Disconnecting QuickBooks

A business may disconnect LineTack from QuickBooks Online at any time, from inside QuickBooks or from LineTack. Disconnecting from LineTack (Disconnect QuickBooks, in the account menu, available to the account owner) stops our reading and writing immediately and deletes the stored access tokens; approved lines then go to the business as a CSV email instead. Disconnecting from inside QuickBooks makes Intuit revoke our access, so we can no longer read from or write to the QuickBooks company. The stored tokens, which then no longer work, stay stored, encrypted, until the account owner also uses Disconnect QuickBooks in LineTack, which deletes them, or asks us to delete them at hello@linetack.com. The customer and job list we copied from QuickBooks (names and billing addresses) stays with the account after either kind of disconnect, because past draft lines refer to it. It is deleted with the rest of the account’s data under section 8, or earlier if the account owner asks us at hello@linetack.com. Charges already written to QuickBooks remain in the business’s books — they belong to the business, and removing them is done in QuickBooks.

8. Keeping and deleting information

Receipt photos are kept for 90 days from the day they arrive, then deleted. We keep a fingerprint (a hash) of each photo, which lets us tell a worker when the same photo is sent twice and cannot be turned back into the picture, and we keep the lines read from it as part of the business’s records below. To have a photo deleted sooner, write to hello@linetack.com.

Message text, drafts and approval records are kept for as long as the account is active, because they are the record of how a charge on the business’s books came to exist. On written request from the business, or within 90 days of account closure, we delete or de-identify what we hold, except where we must keep it to meet a legal obligation or resolve a dispute. When a message arrives from a number that is not on a business’s allowlist, its content is never stored — we keep the sending number, the time, and a hash of the message, which is what lets us count and de-duplicate carrier retries without retaining a stranger’s words. To request deletion, write to hello@linetack.com.

Calculator requests (section 2) are kept for 12 months from the day they are sent, so we can answer questions about the estimate and follow up, then deleted. If you open a LineTack account in that time, the request is kept with the account under the rules above. To have a request deleted sooner, reply to the email we sent you or write to hello@linetack.com.

9. Your rights

Depending on where you live, you may have the right to access, correct, delete, or obtain a copy of your personal information, and to object to some processing. Workers should contact their employer first, since the employer controls the account; we will help. Requests to us go to hello@linetack.com and we will respond within the period the applicable law requires. We will not discriminate against anyone for exercising these rights.

10. Children

LineTack is a workplace tool and is not directed to anyone under 16. We do not knowingly collect information from children.

11. Changes

If we change this policy we will update the date above, and for material changes we will notify account administrators by email before the change takes effect.
