Website terms of use

Registration revision: 2026-10-10-pix-cupom.

Identification and acceptance

MasterFinder is provided by Caetano Hillesheim Sadosiuk, an individual in Brazil. Questions may be sent to suporte@masterfindertool.com.

By creating an account, you accept these Terms and confirm that you have read the Privacy Policy. Recurring card billing authorization is requested separately at checkout and records the displayed text, version, price, and dates. A one-time Pix purchase does not authorize future charges.

Account and security

You must provide a valid full name, email, password, and mobile number and keep your credentials confidential. During the temporary launch exception, the mobile number is stored without a code being sent and is marked as unverified; enter a number you can access because confirmation will be requested later. The waiver does not prove ownership of the number and does not grant additional trials. When the normal flow resumes, confirmation will occur by text message (SMS/RCS) through Twilio Verify. By requesting the code, you authorize that message exclusively for verification. WhatsApp is reserved for future adoption; the channel will be disclosed before each request. The same number may appear on more than one account. Email confirmation is optional and recommended; the link is valid for 24 hours, and lack of confirmation does not prevent account use.

Each person must use their own account. Do not share passwords, sessions, tokens, or configured packages. We may suspend an account for security, fraud, disputes, or violation of these Terms. A suspended account may sign in only to review its status and contact support.

Plan and free period

MasterFinder access costs R$49.90 per month in Brazilian reais. Credit card subscriptions renew automatically. Each Pix payment buys one month of access and requires another purchase after expiry. The free period is available only with a card; eligible coupons can also reduce a Pix payment. When a free-period card offer is active and the account is eligible, the applicable duration is the one shown at checkout before confirmation. Each day is exactly 24 hours. The first card charge occurs after the stated period ends unless canceled. Commercial date and time are shown in Brasília time.

Available coupons may reduce the first commercial card charge or a Pix purchase. On card, they combine with an eligible trial: the free days pass first, then the frozen promotional price is charged; subsequent monthly charges remain R$49.90. On Pix, the promotional amount is paid at purchase and covers one month of access. A quote reserves one slot for 30 minutes, can be removed or changed before payment, and does not guarantee availability after expiration. Coupons with a final amount below Stripe's Pix minimum are unavailable for that method.

Each account may use only one coupon. For cards, creating the subscription keeps the offer allocated; final consumption occurs on the first confirmed commercial payment. Cancellation or failure before that payment releases the allocation. For Pix, the coupon is consumed only after confirmed payment; an expired or failed attempt releases the reservation. Active subscriptions do not receive retroactive discounts. Code, promotional price, and applicable conditions are shown again in the final acceptance.

There is one trial per account, supplied phone number, CPF, or card fingerprint. IP and device are only auxiliary signals. The temporary confirmation waiver does not remove the phone number from this rule. Accounts with a previous subscription or trial, or a confirmed collision, receive no additional trial. If there is a collision, no charge is made by that click: a direct subscription is offered with a new acceptance and confirmation.

An eligible account paying by card starts with the trial; there is no option to skip directly to card billing. Choosing Pix buys one month without a trial. Creating an account neither requires a purchase nor grants free use of the extension.

Renewal and failures

One-time Pix does not renew automatically. The month starts after Stripe confirms payment and ends at the date shown in the account, without a grace period. Displaying a QR code or returning to the website does not grant access. After expiry, access ends until a new purchase is completed.

After the trial, the subscription makes the first commercial charge at the frozen promotional price when a coupon applies, then renews monthly at R$49.90 until canceled. We do not send a reminder three days before the trial ends; the exact end and amounts are shown at the start and remain available in the account.

If the first post-trial charge fails, access ends at the exact trial end. Stripe may make further attempts within its calculated recovery window. That window does not grant access after the trial.

If renewal of an established subscription fails, access may remain in payment_retry for 72 hours. When Stripe announces a third retry for up to 84 hours after the due date, access may be extended through that attempt and its processing, limited to 85 total hours. Retries announced after 84 hours will not be made. The applicable deadline is shown in the account. Recovery preserves the original anchor. Canceling during payment_retry stops new attempts and ends access immediately.

Cancellation, return, and card

Canceling during the trial prevents a charge and keeps access until the free period shown at checkout completes. A normal cancellation is scheduled for the end of the already paid period, with no additional grace period. You may reactivate before the end; after termination, a new subscription receives no trial.

The Stripe Customer Portal lets you manage the card, receipts, and cancellation. A saved card is reused for a new subscription only after explicit confirmation. Changing the card during a trial does not restart or end the trial, and the new instrument is also linked to participation.

There is no pause, plan change, Pix Automático, Apple Pay, Google Pay, or Link in this MVP. Debit, prepaid, or unknown-funding cards are not accepted.

Receipts, refunds, and disputes

Stripe sends an automatic receipt for completed payments. This receipt proves payment but is not a Brazilian service invoice or equivalent tax document.

A full refund is a manual exception and ends access immediately. There are no partial refunds in this MVP. A dispute suspends access and renewal; a win before the end may restore the service, while a loss ends it permanently.

Extension use

Downloading the ZIP neither installs the extension nor grants access. Use requires a compatible browser, privacy consent, a phone number registered at account creation, and active account_access. While confirmation is temporarily waived, the phone remains marked for later verification. The extension researches third-party services in the browser context; you must comply with those services' terms.

Each completed external extraction may record the normalized HTTPS source URL in the MasterFinder backend and increment a global mining counter. Products, ads, and ad contexts in the MasterShop flow are counted separately from direct MasterShop product links used to prepare Meta searches. These records keep no account link or individual history. Manually repeating an extraction increments the counter; creating, completing, repeating, canceling, failing, or letting a search expire does not.

In the flow that prepares Meta searches from a MasterShop product, the URL is sent to the backend for permanent aggregation but is not sent to Google Gemini. The model receives only the extracted product name and selected language. Other processing and retention are described in the Privacy Policy and extension policy.

Results, matches, reputation, and ads support research and do not promise sales, profit, supplier quality, or availability. Meta, MasterShop, Chrome, and other names belong to their owners and do not indicate partnership or certification.

Availability and changes

We may perform maintenance, limit abuse, and temporarily disable new registrations or checkouts. This does not interrupt webhook processing or change existing subscriptions. Price, plan, or commercial-condition changes will be handled in a future round and communicated before they apply to the customer.

Privacy, support, and deletion

Data processing, retention, and deletion are described in the Privacy Policy and extension policy. Account deletion is irreversible, cancels the subscription, and revokes sessions and access. Requests and questions may be sent to suporte@masterfindertool.com.
