Terms of use

In effect since October 6, 2026.

What you're subscribing to

A service that connects to your WhatsApp and automatically transcribes the audio and video in your conversations, and translates the conversations you choose, in both directions.

On the Intelligence plan, the service also includes analyzing the messages in your conversations to generate your business’s sales intelligence: lists and reports on the dashboard and by email, and Smart Actions, alerts on your WhatsApp. Your customers’ data is not published and never leaves your dashboard. It is used to generate your sales intelligence.

What shows up in your contacts' conversations

LangZap writes the transcription and translation inside the conversation itself, including in the conversation of the person you're talking to. These messages start with the symbol "⤷", so the person on the other side can tell they weren't typed by you.

You decide to turn this on and off per contact, with the translate and mute commands, and you're responsible for telling your contacts, if you think it's necessary.

Smart Actions alert only you, in your “You” chat on WhatsApp. These alerts do not go to your contacts: nothing is sent to them, and you are the one who replies.

Payment, cancellation and right of withdrawal

The subscription is monthly or annual. On the Translation annual plan, R$ 286.80 a year (R$ 23.90 a month): with the free trial, in a single charge at the end of the trial; without the trial, in 12 interest-free card installments or in one payment with Pix Automático. Monthly and annual plans are paid by credit card or Pix Automático, with automatic renewal. With Pix Automático, the first payment is made right away and the next ones are debited automatically each cycle, from the account you authorized in your bank app; Pix has no free trial. Payment is processed by a specialized payment company. On the Intelligence plan, R$ 49.90 a month, or R$ 478.80 a year (R$ 39.90 a month).

The subscription renews on its own at the end of each period, monthly or annual, with the same payment method (card or Pix Automático). You can cancel at any time in the panel, before the renewal date. Without payment of a renewal, the service continues for 7 days; then it is paused, and the subscription is canceled after 30 days paused, with the data deleted as described in the Privacy Policy.

Within 7 calendar days after the first charge, including the first one after the free trial, you can cancel and get the full amount paid back, to the same payment method, with no need to give a reason, under art. 49 of the Brazilian Consumer Defense Code.

After that period, you can cancel whenever you want, from your account on the site, with no penalty. The service stops right away and WhatsApp is disconnected, with no prorated refund for the current period. On card installments, the remaining installments stay on your card.

Switching to a larger plan, within the same cycle, charges the prorated difference for the remaining period; switching to a smaller plan takes effect from the next renewal.

After a refund at your request, the same WhatsApp number or CPF/CNPJ can subscribe again only 30 days after the request; the right of withdrawal on each purchase still applies.

Free trial

Anyone subscribing to the Translation plan by card, monthly or annual, can start free: 3 days on the monthly plan and 7 days on the annual plan. Nothing is charged at sign-up.

The charge is automatic, on the registered card, the day after the trial ends: R$ 29.90 on the Translation monthly plan, which then renews every month, or R$ 286.80 in one payment on the Translation annual plan, which renews automatically once a year.

You cancel by the day before the charge, from your account on the website or from the link sent by email, and nothing is charged. Canceling disconnects WhatsApp.

The trial is available once per WhatsApp number and per CPF. Anyone who already used the trial subscribes by paying from day one.

After the first charge, you can cancel whenever you want, from your account on the site, and the service stops right away. Within 7 days after the first charge, you get the full amount back, to the same payment method. After that, there is no prorated refund for the period paid.

On the Intelligence plan, the free trial is 3 days on the monthly plan and 7 days on the annual plan. The charge is automatic, on the registered card, the day after the trial ends: R$ 49.90 a month on the monthly plan, or R$ 478.80 a year (R$ 39.90 a month) on the annual plan. With the free trial, the annual plan is charged once at the end of the trial; without the trial, in 12 card installments or in one payment with Pix Automático.

Usage limits

The plan includes 1,000 minutes of transcription, 1,000 translations and 500 images with text per month, with up to 20 minutes per file. Near the limit you get a warning; once you reach it, processing resumes the following month.

On the Intelligence plan, Smart Actions have a quota of 100 per month; once it runs out, the alerts stop until the following month, unless you buy an extra pack of 50 Actions, valid for 30 days.

One subscription, one number

Each subscription covers one WhatsApp number. To connect another number, you need another subscription.

Permitted use

LangZap is for your own use or your business's, in the conversations of the number you connected, by people over 18. Don't use the service to send unsolicited bulk messages, for any unlawful purpose, or to process a third party's data without a legal basis for doing so.

What we don't promise

Transcription and translation are automatic, done by artificial intelligence, and may contain errors. Don't use LangZap as an official record, evidence, or the basis for a medical, legal or financial decision.

We are liable for damages we cause as provided by Brazilian law; we don't exclude or limit that liability beyond what the Consumer Protection Code allows.

LangZap is not affiliated with WhatsApp

LangZap is an independent service. It is not affiliated with, sponsored by, or endorsed by WhatsApp or Meta.

Changes to these terms

We may change these terms. A material change is announced by email before it takes effect.
