Founder’s Engine — nothing leaves your browser
On Founder’s Engine — Streams → Experiments → Runway. Revenue streams feed your runway math.
Every number in Founder's Engine — every stream, every burn line, every runway assumption — lives in your browser's local storage on your machine. There is no server. There is no account. There is no analytics ping. There is nothing for us to leak if we tried.
The threat model most SaaS ignores
Your revenue is a lever competitors would pay to see. Your runway is a signal investors read against you. Your churn is a story you get to tell in your own words, or not tell at all. Every founder-analytics SaaS is a database of exactly this, in a data center you do not own, run by a company whose incident page you have never read.
The safest number is the one no one else has a copy of.
How the file behaves on the wire
Load the page once. Open dev tools. Watch the network tab. There is nothing there. The Engine makes no fetch, no analytics beacon, no font call, no telemetry. Once cached, it works airplane-mode, forever.
The one exception is if you click a link that leaves the file. The file itself never leaves.
What 'no account' actually means
There is nothing to sign up for and nothing to log into. That means: no password to lose, no email to breach, no session to hijack, no support ticket where a stranger reads your MRR to help you.
It also means we cannot recover your file for you. That is the honest bargain of ownership.
What the file does not do
- No cloud sync.Your data does not leave the machine you typed it into.
- No analytics.We do not know you exist, or which tab you spend most time on.
- No third-party fonts, scripts, or CDNs.Every asset is embedded. The file works offline the moment you own it.
- No auto-updates.The file you bought is the file you have. If we improve it, you decide whether to re-forge.
Questions people ask
Where is my data stored?
In your browser's local storage, on your machine, under your OS user. Export it to JSON any time; it is plain text you can read.
What if my laptop dies?
Same discipline as any file: keep a copy on a drive, another somewhere safe. Export is one click. Restore is one click.
Can Offline.Ltd see anything?
No. There is no back-channel. Not for support, not for improvements, not for anything. We built the file so this is architecturally impossible, not just policy.
The most private business analytics is the kind that never enters a database in the first place.
