About · A short manifesto
What Vaely is built to do,
and not to do.
An app that holds chronic-illness journal entries is, by definition, an app that holds the most sensitive material a person owns. The principles below are the ones we wrote down before we wrote any code, and the ones we hold ourselves to every time we change anything. Eight of them. They are not a marketing claim. They are the source of the architecture.
- I
We do not see what you write.
Not because we promise. Because we built it that way. The on-device language model handles the inference; the local SQLite database holds the entries; the encryption key for backups is never synced to iCloud Keychain. The architecture forecloses the possibility of seeing what you write. That is the design, not the disclaimer.
- II
The journal lives on your phone.
Every entry, every doctor PDF, every encrypted backup, every AI summary stays on the device that produced it. We do not run servers that receive your data because we have not built any. If you delete the App, iOS removes its sandboxed data and the matter is closed.
- III
The AI is a summarizer, never an analyst.
AI outputs are framed as summaries of your own journal entries. "Your journal shows" — never "Analysis indicates." We do not produce risk percentages, do not predict future flares, do not diagnose, do not prescribe. A personal wellness journal can be honest about what it is. Vaely is honest.
- IV
The PDF respects your doctor's time.
Structured for the eleven minutes your doctor has — executive summary up front, the patient's own words at the back. Plain English alongside common medical terms. Headed "Personal Wellness Journal Summary — Not a Medical Document." Designed to be read, not parsed.
- V
The Reduced Rate tier is the worldview.
A separate visible $29.99-per-year tier for full Pro access. No income verification. No proof we ask for. The chronic-illness patients who most need this are also those whom most software is least built to serve. We chose to serve them. The tier exists, and it is listed at the same time as the regular price.
- VI
iOS only, permanently.
The on-device AI that makes voice-first logging possible exists on Apple silicon. We will not ship Android, will not ship a web app, will not split focus across surfaces. Restraint compounds. Better to do one platform completely than three platforms partially.
- VII
We say less, on purpose.
The brand voice is quiet. The website is restrained. The app uses warm amber on cream paper, not red on white. The icon is a single hand-drawn crescent, not a stack of feature badges. The audience — patients reading this at three in the morning during a flare — deserves the quietest interface in the category, not the loudest.
- VIII
And we will earn this every time we change anything.
Every new feature is filtered through a question we wrote down on day one: would adding this make the app more or less worthy of trust at three a.m.? If it would erode the trust, we do not ship it, no matter how good it is in isolation. The principles compound. So does breaking them.
A list, written down so we can be held to it
Things Vaely will never do.
- Sell, share, or rent personal data — to advertisers, brokers, insurers, or anyone else.
- Run advertising of any kind, from any party, for any reason.
- Add a third-party analytics SDK, crash-reporting SDK, or telemetry SDK to the iOS app.
- Display in-app advertising or sponsored health content.
- Use AI outputs that claim diagnostic, predictive, or prognostic capability.
- Charge a fee to access your own data, in any format, ever.
- Hide the Reduced Rate tier behind verification or qualification gates.
- Add a chat widget, AI support bot, or live-chat surveillance system.
- Migrate the journal to a server architecture that introduces remote storage of user content.
- Ship on Android.
A never is a kind of debt — a promise made today that has to be paid forward across every future product decision. We commit to the list above as a reasonable debt to take on.
Who builds Vaely
A small operation, on purpose.
Vaely is built and maintained by tezaapps, a small operation focused on one product. We are reachable at tezaapps@gmail.com. We answer email. We fix bugs. We ship updates. We do not run a press team, a sales team, or a customer-success team — there is one inbox and one set of hands, and the operation is deliberately scaled to what one careful set of hands can hold.
The trade-off of a small operation is the trade-off the patient has already made. The chronic-illness audience knows that small, consistent, careful beats large and noisy almost every time.
The audience deserves the quietest interface in the category,
not the loudest. — Principle the Seventh, kept
Eight principles.
One App Store page.
The principles above are visible to you because they are also the architecture below. The free tier is the place to verify that.
