Privacy policy

Responsibility and scope

DL TECNOLOGIA LTDA. - ME, CNPJ 44.950.578/0001-84, in Mogi Mirim, SP, Brazil, is responsible for this website. For privacy matters, contact contato@dltech.agency. Business inquiries are also available through WhatsApp +55 19 98163-2836.

This policy describes the institutional landing page, its Portuguese and English versions, and the articles, professional website offer, free guides and proposal service on dltech.agency. DLTech apps, games and demos follow the specific policies linked from their pages or stores. Websites built for clients follow the policies of their respective operators.

Project form and email draft

The form lets you enter your name, optional company, project type and a description of your needs. With JavaScript enabled, these fields are processed in your browser to prepare a draft. The form does not send these fields to a DLTech server or record them in a website database. Without JavaScript, use the email link; the draft button remains disabled.

You can review the text, copy it to your clipboard, or open your email app. Copying happens only when you press the copy button. Opening the email link passes the draft to your selected app. Sending the message requires your action in that app.

E-book form

On the 12 ideias para vender mais com tecnologia guide page, the download is unlocked after a form with your name, your business name and field, your WhatsApp number and your biggest challenge today, chosen from a list. The website stores this data with the submission date and, when present in the link you used, the campaign parameters utm_source, utm_medium, utm_campaign and utm_content.

We use this data to unlock the guide and for DLTech to contact you on WhatsApp about the guide and how to apply its ideas to your business. It is stored in a Cloudflare database, where the website is hosted, and a notice with the same data reaches DLTech’s email inbox. We do not sell this data or send it to advertisers. If you no longer want to be contacted, reply to the message or email contato@dltech.agency.

To prevent abuse, Cloudflare limits repeated submissions from the same IP address at the time of submission; the IP address is not stored with the form. During the visit, browser session storage keeps the campaign parameters (key dltech-guide-campaign) until the tab is closed. After saving a registration, the server creates a random receipt in the dltech_guide_receipt cookie, valid for up to 30 minutes. It contains no form data and is consumed when measuring the registration, preventing duplicate counts on reload. If you arrived through a Taboola ad, the click identifier is passed to the confirmation page, where it is used to measure the registration unless you have turned measurement off.

Interest in the professional website offer

The Professional website page records your name, business, WhatsApp number and intended start timing. By using the submit button, you request contact from DLTech on WhatsApp about this inquiry, as explained next to the button. We record the timestamp and form version to identify this request. This information is stored on Cloudflare infrastructure with a timestamp, submission identifier, offer version and ad-source parameters when available. DLTech receives an internal email notice to respond to your request. Submitting the form does not purchase the service or send an automatic WhatsApp message.

We use this information to understand your project, respond and agree on conditions before any purchase. The contact channels, retention periods and rights in this policy apply. For the browser session, the page stores source parameters and a submission-confirmation flag, without storing your name, business or telephone number in browser storage. A random technical receipt containing no form data lets an enabled measurement system count a saved registration once.

This offer uses the Meta pixel to measure visits, reaching the form, starting to fill it in, clicks on the WhatsApp button and saved registrations. A click on the button indicates interest in contact; it does not confirm that a message was sent. It follows the preference already saved on guide pages; a previous opt-out remains effective. You can change it through Ad measurement preferences in the page footer. Form fields are not sent to the pixel. Local previews and identified QA tests are excluded from measurement.

Website redesign inquiries

The Website redesign form records your name, WhatsApp number, public website address, requested improvements and optional start timing. Query parameters and fragments are removed from the submitted website address. The inquiry is stored separately from the fixed-price website offer on Cloudflare with an identifier, timestamp, form version and campaign source. An internal email alerts DLTech to prepare a quote and reply on WhatsApp. Submission does not purchase a service or automatically send a WhatsApp message.

The measurement controls, retention periods and privacy contacts described for the professional website offer also apply. Form fields are not sent to the pixel. A technical receipt lets an enabled measurement system count a saved inquiry once. Only source parameters and a confirmation flag are stored for the browser session, without the completed form fields.

Professional proposals

A professional office may use DLTech to prepare and present a private proposal containing the recipient's name, services, terms, prices and professional details. The office determines the content and receives notices; DLTech operates the service on Cloudflare. For the office's use of the information and retention, contact the office. For platform questions, contact contato@dltech.agency.

Access requires a link and a code. A random session cookie maintains access for up to 24 hours and does not contain a name or email. The service records the first authenticated access and may notify the office by email. If you accept, it records your name, email, date, version and selections; the office receives a notice. Cloudflare may process IP addresses to limit attempts, but the IP is not included in the acceptance record. Retention depends on the contractual relationship and applicable obligations; this version does not automatically delete proposals after a fixed period.

Email and WhatsApp contact

When you send a message, you share your email address or phone number and the content you choose to provide. This information is used to reply, understand your needs and assess or prepare a proposal you requested. For steps before entering a contract, at the data subject’s request, Brazil’s LGPD provides the basis in article 7, V.

Email is processed through the services used to exchange messages. The WhatsApp link opens a WhatsApp/Meta service, which processes data under its privacy policy. The website button does not automatically send a message. Avoid including confidential documents, health data or other sensitive information in the initial briefing.

Language and browser storage

The language selector saves your Portuguese/English preference in browser local storage under the key dltech-language. On the first visit, the website checks the language reported by your browser. You can remove the preference through your browser’s website data settings; automatic language selection may then run again.

Hosting, security and performance measurement

Cloudflare delivers and protects the website. Requests pass through its infrastructure, which may process IP addresses and technical information needed for delivery, operation and security. See Cloudflare’s privacy policy.

The website uses Cloudflare Web Analytics to measure page visits and performance. A Cloudflare script sends technical metrics, such as page views and load times, to the measurement service. According to the service documentation, this measurement is designed without collecting or using visitors’ personal data. This is separate from the technical processing needed for hosting.

The Google tag on the website-offer article loads only with your permission. Meta’s and Taboola’s pixels load on the guide pages, and you can turn them off, as described below. Language storage remains local to your browser. Cloudflare’s infrastructure may use security mechanisms, including cookies when protection features require them; see Cloudflare’s cookie documentation.

Optional ad measurement on the website-offer article

On the website-creation offer article, you can allow or decline Google Ads measurement. The Google tag loads only after your permission. If you decline, the article and contact links still work.

With permission, Google may receive technical data such as IP address, browser information, the page URL, advertising-click identifiers and the WhatsApp-button click event. Measurement uses cookies to attribute that click to ads. A button click indicates contact intent; it does not confirm a message was sent or a sale occurred. The website does not send Google your conversation content or the name, email or phone number you enter. We do not enable enhanced conversions or ad personalization in this integration.

Your choice is saved in browser local storage under dltech-ads-consent-v1 for up to 180 days. You can change it using Preferências de cookies de anúncios at the article footer, or clear the browser’s website data. On withdrawal, the page reloads without the tag and attribution cookies accessible to the site are removed. Withdrawal does not undo earlier processing. For Google’s processing, including storage and data transfers, see its privacy policy and partner-sites data information.

Ad measurement on the guide

On the guide pages, we use Meta (Facebook/Instagram) and Taboola pixels to learn which ads bring visits and registrations. The pixels load when the page opens. We carry out this measurement based on DLTech’s legitimate interest in evaluating its ads (LGPD, article 7, IX), and you can object to it by turning measurement off. The guide and contact links keep working.

While measurement is on, Meta and Taboola may receive technical data such as IP address, browser information, page URL, the ad click identifier and the page-visit and successfully saved registration events. Measurement uses cookies to attribute these events to ads. The website does not send Meta or Taboola your name, business name, WhatsApp number or the challenge you chose.

To turn it off, use Preferências de cookies de anúncios (ad cookie preferences) in the guide pages’ footer. Your choice is kept in browser local storage under the key dltech-guide-ads-consent-v2 until you change it or clear the site’s data in your browser. Turning measurement off reloads the page without the pixels and removes the cookies accessible to the website. This does not undo processing already carried out. The integration does not enable advanced matching or automatic form collection. For Meta’s processing, see its privacy policy; for Taboola, see its privacy policy.

External links and services

Links to LinkedIn, WhatsApp, stores and product websites lead to external services. When you visit them, you use those environments and their own policies. Landing-page fonts and images are served from this domain; measurement resources are provided by Cloudflare, by Google on the offer article when permitted, and by Meta and Taboola on the guide pages while measurement is on.

Information retention and your rights

E-book and website-interest form data is kept for up to 12 months after our last contact with you, or until you ask for deletion, unless a business relationship requires a longer period.

Messages sent through the contact channels remain in the communication environments. The need to retain them depends on the request, any business relationship and applicable obligations. You can contact the privacy address for information about retention and processing of your messages.

The LGPD provides rights including confirmation and access, correction, sharing information and, where legally applicable, deletion, portability, objection and withdrawal of consent. To exercise a right, email contato@dltech.agency. The request is assessed according to its nature and applicable time limits. Identity verification may be needed to protect your data, using only information relevant to the request.

You can also contact Brazil’s National Data Protection Agency (ANPD). See the official LGPD text.
