Last updated: 14 August 2026 (name change).
This policy describes how Walkstamp works today: with no processing server and no user accounts.
Until 14 August 2026 this service was called ClipContext. Only the name changed — the controller, the legal bases and the retention periods below are exactly the same.
Walkstamp is offered by Produtize Produtos e Serviços Inteligentes Ltda., a company registered in Brazil under CNPJ 48.417.292/0001-99, acting as the controller of the small amount of personal data described in this policy, under Brazilian Law 13,709/2018 (LGPD).
Data subject requests, questions and privacy complaints: privacidade@walkstamp.com. This is also the channel for the data protection officer (LGPD art. 41).
We do not receive your videos, your audio or your transcripts — that has not changed and will not change on the free plan. We use no cookies and there is no login. Since 14 August 2026 there are two things that are recorded, both described in detail below: a page-view count with no cookie and no identifier, and a count of three usage milestones, also anonymous. If you leave your e-mail on the pricing page, that is personal data — and it is the only piece of it here.
Walkstamp is a static page. When you choose a video, it is read directly from your device by the browser and stays there. Extracting the images, reading the audio, transcribing it and assembling the PDF all happen entirely on your computer, using its processing power.
The file is never sent to us. There is no temporary copy on our systems, because no system of ours is involved in the processing.
A tool nobody knows is being used cannot be improved in the right place. So there are two measurements, and both were designed not to know who you are:
If your browser sends Do Not Track or Global Privacy Control, the three milestones are not sent. And the offline version — the single file you download — is built with no measurement address inside it at all: it talks to nobody, and you can check that by searching the file for “supabase”.
The pricing page has an optional e-mail field. If you fill it in, the address and the page language are stored in a database of ours, with the date. It is the only personal data here, and it:
The page makes a small number of connections to third-party services, and none of them carries your content:
These third parties have their own policies and may record technical connection data, such as your IP address, in the same way that happens when you visit any website.
When you use the recording feature, the browser asks your permission to capture the screen and, if you tick the option, the microphone. The image and both audio channels are processed on your own computer: frames are extracted and the audio is transcribed right there. The video is never written to any file — not on our side, which does not exist, and not on your disk. Nothing from that capture is transmitted to us.
If the button to open a video from Google Drive is available and you use it, the browser connects to
Google to authenticate and download the file you pick. The file goes from Google straight to your
browser, without passing through any server of ours. We request the most restricted permission
that exists (drive.file), which grants access only to the files you select in the Google
window — never to the rest of your Drive. Until you click that button, no connection to Google is made.
If you use automatic transcription, the browser caches the downloaded model so it does not have to be downloaded again. That file stays on your device, under your control, and is removed when you clear your browsing data. We have no access to it.
We use no first-party or third-party cookies — not for tracking, not for advertising, not for measurement. The page-view count and the three milestones described above work without cookies and without any identifier that persists between visits, which is precisely why there is no cookie banner on this site: there would be nothing to consent to.
The service is not directed at children under 13, and the notification list should not be filled in by them. We have no way to verify age — there are no accounts. If you know a minor left their e-mail, write to privacidade@walkstamp.com and it will be removed. Beyond that we hold no data about minors, because we hold no data about anyone: the video never leaves the device.
What is processed, why, on what basis and for how long:
| Data | Purpose | Legal basis | Retention |
|---|---|---|---|
| Notification-list e-mail | Telling you when the paid plan exists | Consent (LGPD art. 7 I / GDPR art. 6(1)(a)) | Until you withdraw it, or 24 months unused |
| The three usage milestones | Knowing where the tool fails, and improving it | Anonymised data (LGPD art. 12); if in doubt, legitimate interest | 18 months |
| Page views | Knowing how many people arrive, and from where | Anonymised data (LGPD art. 12); if in doubt, legitimate interest | As per Vercel's policy |
| Web server access logs | Security and legal obligation | Legal obligation — Brazilian Internet Civil Framework, art. 15 | 6 months |
The milestones and page views were designed not to identify anyone; should an authority nonetheless treat them as personal data, the basis is our legitimate interest in maintaining and improving the service, and you may object through the contact above.
The notification-list e-mail and the usage milestones sit in a database hosted by Supabase in the São Paulo region — that is, on Brazilian soil. The site itself is hosted by Vercel, whose network is global: technical access logs and the page-view count may be processed outside Brazil, which constitutes an international transfer under LGPD art. 33, covered by the provider's own contractual clauses.
Your videos are in none of those places, because they never leave your device.
The LGPD (Law 13,709/2018) grants you, at any time and free of charge:
In practice, here that almost always means one thing: taking your e-mail off the list. Write to privacidade@walkstamp.com — we reply within 15 days, and for that request the removal is immediate. We ask for no document and no justification: the address writing to us is itself the proof that it is yours.
You may also complain to the Brazilian data protection authority (ANPD), or to your local supervisory authority, if you believe your rights were not respected.
If this policy changes, the date at the top will be updated. Material changes — especially any move to start collecting data — will be announced on this page, with the date at the top updated.
