Tideshift Ventures is a software studio building privacy-first products. We believe your data should stay yours — not monetized, brokered, or silently harvested.
Incorporated as an LLC in Delaware, we design tools that work locally on your device whenever possible, use end-to-end encryption when sync is needed, and never sell user data. Every product we ship is built to earn trust through transparency, not terms of service.
Data stays on your device by default. No cloud accounts required.
When sharing is needed, only you and your recipients can read the data.
We make money from products, not from selling your information.
Tools we've built and shipped.
Digital loyalty cards for Apple Wallet and Google Wallet.
Replaces paper punch cards with digital stamp passes stored in Apple Wallet and Google Wallet. Customers scan a QR code once — no app download needed. Businesses track visits, stamps, and redemptions from a simple dashboard. Setup takes under five minutes.
stampd.shop →On-device jewelry appraisal powered by local AI.
Chrome extension that uses on-device AI to help assess jewelry value and authenticity. All analysis runs locally in the browser — images never leave your machine. Built on Chrome's built-in AI capabilities for privacy-preserving evaluation.
Zero-based budgeting that keeps your finances private.
A mobile-first budgeting app with the same proven methodology as YNAB, built local-first. Your income, expenses, and financial goals stay on your device — no bank connections required, no cloud sync unless you opt in with end-to-end encryption.
