1. What this list is
Arcavelo uses a small number of outside companies (“subprocessors”) to run the app. Each one receives only the data it needs to do its job, is bound by its own terms to protect that data, and may not use it for its own purposes such as advertising. None of them is permitted to use your data to train AI models. This list supplements the Privacy Policy.
2. Current subprocessors
| Provider | What it does | Data it receives | Location |
|---|---|---|---|
| Neon | Hosts the PostgreSQL database that holds your account and app data, with a short rolling backup history. | All account and app data described in the Privacy Policy. | United States |
| Vercel | Hosts and serves the app, runs scheduled background jobs such as Google Tasks sync, stores uploaded files privately (Vercel Blob), and counts cookieless page views on the public pages (Vercel Web Analytics). | Requests to the app, standard request logs, uploaded syllabus files (deleted within 7 days), and uploaded class banner and background images. | United States (pages delivered through a global network) |
| Google Sign-In, Google Calendar and Google Tasks sync when you use them, and read-only Gmail access when you connect it for Arc. | Your Google account identity, the calendar events and tasks the app creates, reads, or moves for you, and the email Arc reads for you. | United States | |
| Apple | Sign in with Apple, only if you choose it. | Your Apple account identifier, the name you share on your first sign-in, and your email address or a private relay address. Nothing else from your Apple account. | United States |
| Anthropic | Provides the AI model behind syllabus import and Arc, including Arc's public-web research, only when you use those features. | Uploaded or saved extracted syllabus content, your question to Arc, optional Arc routine preferences, the Arcavelo data, calendar event details, and email content needed to answer it, and general-topic web-search queries and results when Arc researches a question. | United States |
| Stripe | Processes payments for paid plans and manages subscriptions, invoices, and receipts. | Your email address, payment details you enter on Stripe's page, and your plan and billing history. | United States |
| Resend | Sends Arcavelo's welcome and reminder emails. | Your email address, your first name, and the content of each email we send you, which can include the names and due dates of your upcoming assignments. | United States |
| Sentry | Error monitoring, so bugs can be found and fixed. | Technical error details such as stack traces and the page involved. Request bodies, cookies, authorization headers, and IP addresses are removed before sending. | United States |
3. Changes to this list
Before a new subprocessor starts receiving personal information, we will add it to this page and update the “Last updated” date. If a new subprocessor would receive your academic content or Google data, we will also tell you in the app beforehand. Questions about any provider can be sent to support@arcavelo.app.
