Does Tanda Work Offline and Keep Your Financial Data Private?
Yes to both, with one caveat worth knowing up front. Tanda is built offline-first: logging works with no internet at all, and in full privacy mode your voice, words, and expenses stay on your phone. The exception is sign-in and crash reports, which still use the internet even in the most private setting.
Offline logging: what works without a connection
Tanda is a voice-first finance app — you tap once, say what you paid, and it fills its own ledger. That logging flow does not depend on a network connection.
According to the site, logging works with no internet at all, and the app is described as offline-first, syncing when you are back online. In practice that means:
- You can record an expense in airplane mode or with no signal.
- Entries are held on the device and sync once connectivity returns.
- The app's own description of the model is "offline-first, syncs when you're back."
One dependency sits outside Tanda's control: on-device speech recognition relies on the languages your phone has installed. If your phone lacks the language pack for the language you're speaking, voice input may not behave as expected — that's a phone setting, not a network issue.
Privacy: you choose how much stays on your phone
Tanda frames privacy as a dial rather than a fixed setting. The site's own framing is "as private as you want" — you pick how much stays with you.
| Mode | What stays on your phone | What uses the internet |
|---|---|---|
| Full privacy | Voice, words, and expenses | Sign-in and crash reports |
| Fast | Depends on the setting you choose | Sign-in, crash reports, and whatever the faster mode requires |
In full privacy mode, the site states plainly that your voice, your words, and your expenses stay on your phone. It also states that sign-in and crash reports still use the internet — so "fully offline forever" is not the claim, and it's worth reading the two modes before deciding which to use.
The trade-off is explicit: full privacy keeps everything local, while the faster option is described as letting the app "work faster." The site does not detail exactly what the faster mode transmits, so if that distinction matters to you, treat it as the deciding question rather than assuming the two modes are equivalent.
What else the app does
- Voice logging in ten languages: Arabic, Dutch, English, French, German, Indonesian, Italian, Portuguese, Spanish, and Turkish.
- Two-way voice: you can ask about your money out loud and hear the answer back in the language you asked. The site's example: "How much on food this month?" → "138 USD on food this month."
- Multi-currency: EGP, Gulf currencies, EUR, and USD.
- Nine categories, sorted automatically.
- Budgeting three ways: a monthly cap, a daily limit, and per-category limits. The site's sample shows a monthly budget of 820 of 1,200, a daily limit of 34 of 50, and category caps like Food 200/320 and Transport 60/130.
How to decide
Choose Tanda's full privacy mode if keeping voice and expense data on-device is your priority and you can accept that sign-in and crash reports still reach the internet. Choose the faster mode if responsiveness matters more to you than keeping everything local — but note the site doesn't spell out what that mode sends, so that's the gap to resolve before committing.
Either way, offline logging works. The privacy question isn't whether Tanda can run without a connection; it's which of the two privacy modes matches how you want your data handled.
