Data received
When you submit a CSV, an XLSX converted in the browser or a pasted list, the application receives the URLs and the other columns in the file. Avoid including names, email addresses, phone numbers, identification documents or other personal data that is not needed to find the thumbnails.
Purpose
The data is used to validate the file, process URLs, track the batch, generate the result and prevent abusive automated use. The network address may be used temporarily for request limiting and security validation.
Optional metrics and consent
Google Tag Manager is loaded only after an affirmative choice. The preference is kept in the browser local storage and can be changed through Privacy preferences. Telemetry accepts only counts and closed categories. URLs, link content, file names, sheet names, batch identifiers, credentials and typed text are not placed in the metrics layer.
Legal bases and rights
Optional metrics processing is based on consent. Strictly necessary security, abuse prevention and operational continuity controls may rely on legitimate interests or applicable legal obligations. Data subjects may request confirmation, access, correction, information, objection, deletion and consent withdrawal, as applicable.
Storage and access
Input files, status information and results are stored privately. The browser receives a random batch credential and keeps it in local history. Anyone who receives a shared address containing that credential can open the same batch.
Final thumbnails may be published at a public delivery address for use in spreadsheets, reports and dashboards. Do not submit links to content you are not authorized to process.
Retention
| Category | Operational period |
|---|---|
| Input file | Up to 7 days |
| Credential, status and result CSV | Up to 90 days |
| Published thumbnails and cache assets | Up to 365 days |
These periods are configured maximums. An item may be removed earlier because of technical unavailability, a valid request, a source change or maintenance.
Services used
The operation may use Cloudflare for hosting, storage, queues, abuse protection and human verification, and GitHub Actions as a processing contingency. Platforms associated with submitted links receive the requests required to locate the public thumbnail. Google Tag Manager participates only when optional metrics are allowed.
Security
Batch access uses a random identifier and a separate credential. During normal navigation, the credential is not sent to the server as part of the URL because it remains in the address fragment. Do not publish the complete batch address on open pages.
Sharing, transfer and controller
Providers may process data in other countries under their contracts and policies. The application does not sell submitted data. Kamale.ad acts as the controller for this product and receives requests through the official channels listed below.
Requests
Removal, privacy or security requests must be sent through the official channels at kamalead.com.br, including the batch or thumbnail URL and the reason for the request.
