# The Brink Labs — Software That Answers To You > An independent software lab building offline-first tools you buy once and own forever. Publisher of MyneWallet for Android and six private finance instruments. Canonical: https://thebrinklabs.com/ Source: The Brink Labs · support@thebrinklabs.com · Last reviewed 2026-09-07 --- Independent Software Lab ## We Build Software That Answers To You. The Brink Labs is an independent software lab. We build tools that run on your own device, keep your data where you put it, and are bought once rather than rented forever. Everything below is either shipped or not mentioned. The Doctrine ## Four Commitments, Written As Constraints. A principle you can break at will is a preference. These four are written into the architecture, which is what makes them checkable rather than reassuring. ### On-device by default If a feature can run on the phone, it runs on the phone. The network is a privilege we ask permission for, never an assumption we design around. This is why there is no sync — a copy you cannot see is still a copy. ### Bought once, owned forever A tool you open daily makes an excellent subscription and a poor deal. We charge once. If the company disappears tomorrow the software keeps working, because nothing about it depends on us still being here. ### No advertising, no telemetry There is no analytics SDK, no attribution SDK and no crash reporter phoning home. We do not know how many screens you opened today, and we have built ourselves no way of finding out. ### Correct before clever Arithmetic about somebody’s money is not a place for approximately. Every figure is checked against an independent implementation before it ships, and a feature waits if the maths is not settled. A privacy policy is a promise about what a company will choose to do. An architecture is a statement about what is possible. What We Ship ## One App. Six Instruments. A small catalogue, deliberately. We would rather be answerable for a few things that are finished than for a shelf of things that are nearly working. A budget planner and expense tracker that never asks for a bank login, never sends your ledger anywhere, and keeps working in airplane mode — because there is nowhere for it to phone. - Zero-based envelope budgeting — every unit of income assigned before it is spent. - Two-tap capture — no network round-trip between spending and logging. - An analysis engine, not a pie chart — net worth, obligations and a 30-day outlook. - AES-256 backups to your own Google Drive, encrypted before they leave the phone. Free to use. One-time unlock for the full engine. · Read what it refuses to do → Small, exact tools for the questions money raises. Each runs entirely inside your browser, boots on a worked example, and is checked against a second implementation before it ships. No account, no cookies, nothing uploaded. · Open the index → Engineering Standard ## Tested Like Infrastructure, Not Like An App. Personal finance software fails quietly. A wrong figure looks exactly like a right one, so the only defence is refusing to trust the first implementation of anything. We publish the failures too. The build report for this site lists eight defects found and fixed in the last pass, including two that had been live for weeks — because a standard nobody can audit is a slogan. Where To Start ## Stop Renting. Start Owning. If you want to see how we build before you install anything, the instruments are the honest preview: same architecture, same refusal to phone home, no sign-up to find out. --- This is the markdown representation of https://thebrinklabs.com/, published so that AI agents and answer engines can read the page without parsing HTML.
