Privacy policy
Last updated: November 1, 2026
Sierra Lingua Online (sierralingua.com) provides Venezuelan visa, passport and translation services; Neftaly handles the cases. The platform (the form, your online case, payments and storage) is operated by MacroSeer Inc., 5351 Main St, Waitsfield, Vermont 05673, United States, for Sierra Lingua. This page explains what data we receive, what we use it for, and how to ask us to delete it.
What data we receive
- Intake form: your name, email, WhatsApp, the service you are interested in, your language and your agreement to be contacted.
- Questionnaire and case: the answers you give (for example visa type, nationality and travel dates) and the documents you upload (passport, photos and other requirements), plus the messages you write on your case.
- Payments: card payments are processed by Stripe. We receive the name, email, amount and payment status; your card details never pass through our servers.
- Appointments: if you book a guided session or a call, Calendly receives the booking details.
- Minimal technical data: IP address and browser in the hosting provider's logs, a bot check on the form (Cloudflare Turnstile) and cookieless visit statistics (Vercel Web Analytics) on the form and case pages.
What we use it for
- To reply to you and deliver the service you bought: review your documents, prepare your application and, with full service, file it for you in the official portal, only with the authorization you tick before paying.
- In the AI-assisted review, your documents are read by an AI model (Anthropic) to prepare your fix list; they are not used to train models.
- To send the emails about your case (the private link, the receipt, notices and reminders) and, only if you agreed, WhatsApp messages about your case.
- To take payment, issue receipts, process refunds and keep the accounts.
Who we share it with
- Neftaly (Sierra Lingua), who handles your case.
- The Venezuelan government, only what you authorize us to file in the official portal. We never collect or touch the government fee.
- The providers that run the service, each only for its task: Vercel (hosting), Supabase (database and files), Stripe (payments), Resend (email), Anthropic (AI review), Calendly (appointments), Cloudflare (bot check) and Meta WhatsApp Business (if you agreed to WhatsApp).
- We do not sell your data or use it for advertising.
How long we keep it
- You can delete your documents at any time from your case. Otherwise they are deleted automatically 30 days after the case closes, or after 7 days if the case was left as an unfinished draft.
- Questionnaire answers are deleted when the linked case closes, or 90 days after a request that did not go ahead.
- Payment records and receipts are kept as long as accounting requires.
Your case is private
- Your case opens with a private link that only you receive. Anyone with that link can see your case, so do not forward it. Case pages do not appear in search engines and do not share their address with other sites.
Your rights
- You can ask us for a copy of your data, or to correct or delete it, by writing to eric@macroseer.com. If we delete a case with a service in progress, that service stops.
