Sync.com?

NOT REALLYA prototype of the interface is possible, but the durable product depends on difficult systems beyond the UI. Build a safer adjacent workflow instead.

BUILD FIRST

A non-sensitive or read-only version of the core experience
A manual review step wherever correctness or trust matters
A narrow companion tool that removes a real piece of work

LEAVE FOR LATER

Regulated decisions, payments, or irreversible actions
Claims of correctness, compliance, or uptime that the MVP cannot support
Sensitive integrations until security, support, and auditability are ready

RESEARCH NOTES

What this tool actually does.

Checked 2026-09-06

Sync.com is a privacy-focused Canadian cloud storage service (trusted since 2011) that markets itself as 100% private via end-to-end encryption. It offers synced folders that integrate with Windows File Explorer and macOS Finder, plus web and mobile apps (iOS/Android). Key features include files-on-demand (cloud-only placeholders), version history and deleted-file recovery (60–365 days depending on plan), advanced share controls (read-only, expiry, download limits, notifications), and Sync Vault for archiving cloud-only files. Plans target individuals (e.g., 150GB, 5TB, 1TB, Unlimited) and teams/businesses with role-based access control, admin delegation, custom branding, and compliance certifications (SOC 2 Type 1, GDPR, HIPAA, PIPEDA). Pricing is per-month or per-user per-month with annual discounts and trials/money-back guarantees. No independent testing of the product was performed;

RESEARCHED BUILD PROMPT

Give this to your coding agent.

Build a self-hosted, zero-knowledge cloud sync service inspired by Sync.com's core workflow: users install a desktop client that syncs a local folder with encrypted remote storage, access files via web/mobile, and share encrypted links with granular controls. The app must implement E2E encryption (client-side AES-GCM + RSA or X25519 key exchange, keys never leave the client), folder sync with incremental uploads and conflict resolution, files-on-demand placeholders for desktop, version history/trash retention (configurable 30/60/180 days), and share links with read-only, expiry, and download limits. Use Node.js/Python backend with Postgres + S3-compatible storage, a Tauri/Electron desktop client for Windows/macOS, and a React web app. Include user auth (2FA), team workspaces with roles, admin audit logs, and a CLI for bulk operations. Do NOT copy Sync.com's brand, logo, or UI; design original branding, but keep the familiar folder-sync mental model. Out of scope: mobile native apps (use responsive web PWA), Office-style collaborative editing, and third-party integrations. Deliver a README covering setup, architecture diagram, threat model, and main limitations (no key recovery, no server-side search/thumbnails, sync only via watched folder). Emphasize that this is an educational implementation, not a replacement for a production privacy service.
