What makes a finance app private?
It stores your financial data on your own device, does not sell data, does not use third-party tracking tools, and is transparent about which data is sent off. Because spending data is highly sensitive, this is the set of criteria you should check carefully before installing any app.
Criterion 1 — Where is data stored?
Favor an app that stores financial data on the device rather than forcing everything into the cloud. With Sakura, according to the privacy policy, all transactions, wallets, and budgets are stored locally on the iPhone with SwiftData and by default never leave the device. In short, Sakura processes voice on device, and your transactions are not shared unless you enable sync.
Criterion 2 — Does the app sell data or track you?
Read the “what the app does not do” section carefully. A privacy-respecting app will clearly state that it does not sell data, does not use advertising identifiers, and does not embed third-party analytics SDKs such as Firebase or Mixpanel.
Criterion 3 — Which data is actually sent off?
Transparency matters more than slogans. An app should state clearly which part is sent to a server and why. With Sakura, only the text transcribed from your voice is sent off for the AI to analyze, while the original audio recording is never stored or transmitted.
Criterion 4 — Does it require an account?
An app that does not require an account is a privacy plus, because you do not hand over an email or identity. Sakura, for instance, does not require you to create an account to start using it.
How can you tell whether a finance app respects your privacy?
Read the privacy policy to see where data is stored, whether it is sent to a server, whether it uses third-party analytics, and whether the app requires you to create an account. A clearly written, specific policy is usually a good sign; a vague or hard-to-find one is worth being wary of.
