Privacy Policy

Sonanta is built so you know where your money goes —and so that only you know. This policy explains, in plain language, what data is handled and what isn't. The short version: your financial information lives on your iPhone; Sonanta doesn't collect it on any server, doesn't sell it, and shows no ads.

01Data controller

The controller of personal data is Jesús Eduardo Hernández Martínez, responsible for the Sonanta application, located in Xalapa, Veracruz, Mexico. You can reach us at hola@sonanta.com.mx.

This policy is governed by Mexico's Federal Law on Protection of Personal Data Held by Private Parties (LFPDPPP) and its regulations.

02What data is handled

Sonanta handles the minimum possible amount of information, and in general it never leaves your device:

• Your expense data: amounts, merchants, categories, payment methods, dates, notes, shared-expense splits, budgets, subscriptions, and the Experiences —a trip, a wedding, a move— you use to tag a period. Stored locally on your iPhone.
• Voice audio: when you dictate an expense, the audio is transcribed on the device and is neither transmitted nor kept as a file.
• Receipt photos: stored as files on your device, encrypted by the system, and read with local text recognition. They are never uploaded to any server.
• Apple Pay payments: only if you turn that feature on. See section 05.
• What the app learns from you: associations such as "OXXO is Groceries" or "the red one is my Santander card", derived from your own corrections, and the per-merchant confirmation count that decides when an Apple Pay payment may file itself. They live with the rest of your data and are deleted with it.
• Anonymous usage data: product metrics from a closed list (for example, whether a capture was saved or edited, times and rates) that do not identify you and contain no amounts, merchants, or transcripts. This data stays on your device and is not sent to any server.

Sonanta does not ask you to create an account, and does not collect your name, email, phone number, location, or contacts.

03What it's used for

The data you record is used only to provide the service: showing and organizing your expenses, interpreting your voice, generating summaries and —if you enable Sonanta Pro— watching your budgets, warning you about upcoming charges, answering your questions, and building your report. Anonymous usage data helps us understand how the product behaves and improve it, never to profile you.

04On-device processing

Speech recognition, the interpretation of your sentences, receipt reading, learning, and every calculation —summaries, budgets, reports, and answers— happen on-device. Sonanta works offline and does not rely on servers of ours to operate. We use no cloud language models: your financial information does not travel over the internet to us or to third parties.

05Apple Pay payments (optional)

Sonanta can suggest an expense right after you pay contactlessly with your iPhone. You turn that feature on by creating an automation in Apple's Shortcuts app; if you don't create it, nothing happens.

When it is active, Shortcuts hands Sonanta four details of the transaction: the merchant name, the amount as text, the card name as Wallet displays it, and the date. That message is stored encrypted in the app's shared container, on your device, and waits in an inbox on the capture screen until you review it.

Once you have confirmed the same merchant several times, Sonanta stops asking and saves the expense directly, telling you so with an undo option. That threshold is computed from your own history, on the device, and is deleted with it.

Sonanta does not connect to your bank accounts, does not ask for credentials, and never receives card numbers. You can turn the feature off at any time by deleting the automation in Shortcuts.

06iCloud backup

If you leave it enabled, Sonanta backs up your expenses and catalogs to your own iCloud account, encrypted, so they survive a change of phone. That backup runs through Apple's services, under your account's control and Apple's privacy policy. We cannot access or see it.

You can turn it off inside the app, in Settings > My data > Back up to iCloud, or from your iPhone's iCloud settings. Usage metrics are never backed up, and receipt photos do not travel in that backup: they stay as files on the device.

07Widget, iPhone search and alerts

• Home Screen widget: to draw it, the app writes only two already-computed figures —spent today and this month— into a shared container on your device. No individual expenses live there.
• iPhone search (Spotlight): so you can find an expense from system search, the app publishes the merchant, category, amount, and date to your device's local index. That index is never sent anywhere and is deleted with the app. What you dictated is never indexed.
• Alerts: reminders for upcoming charges, budgets, Experiences that just ended, and the monthly report —including the one you ask to arrive on a fixed day— are scheduled on your device. We do not use notification servers to send you messages or campaigns.

08Permissions (microphone, camera, speech, alerts)

Sonanta asks only for the permissions it needs, and only when you use them:

• Microphone and speech recognition: to log expenses by speaking. Audio is processed locally.
• Camera: to photograph receipts. The photo is processed on the device.
• Notifications: for the alerts you configure (charges, budgets, reports, Experiences).

You can revoke these permissions at any time in Settings > Sonanta on your iPhone; some features will stop being available, but the app will keep working with manual entry.

09Third parties and transfers

Sonanta does not sell, rent, or share your personal data with third parties for commercial purposes. The app integrates no ad networks and no third-party analytics SDKs (for this website, see section 10). The only third party involved is Apple —as provider of the operating system, iCloud, Shortcuts, and the App Store— whose processing is governed by its own terms.

10This website

Everything above describes the app. This site (sonanta.com.mx) uses Umami, a web analytics tool that measures, anonymously and in aggregate, how many visits each page receives and which links are clicked —for example, how many people tap "Download on the App Store" or how far down they read.

Umami sets no cookies, builds no profiles, and cannot identify you or track you across sites. It does not store your IP address: it uses it momentarily to generate an anonymous identifier that is discarded daily. That is why this site needs no consent banner. You can read Umami's privacy policy.

This measurement only tells us whether the page is understood; it is not used for advertising and is never combined with app data. If you would rather not appear in it, any content blocker stops it without affecting the site.

11Purchases and subscriptions

Sonanta Pro is purchased by subscription through Apple's App Store, monthly or yearly. Apple processes the payment and tells us only whether your subscription is active: we do not receive or store your card or payment details. Billing, renewal, and refunds are governed by Apple's policies.

12Retention and deletion

Since your data lives on your device, you control it. You can delete expenses one by one or use "Erase all my data" in Settings > My data, which removes expenses, categories, payment methods, subscriptions, budgets, Experiences, what the app learned, receipt photos, and local metrics, leaving the app as freshly installed. Uninstalling the app also deletes local data. The iCloud backup is managed from your Apple account.

13Your rights

Under the LFPDPPP you have the right to access, rectify, cancel, or object to the processing of your data, and to withdraw your consent. Since Sonanta keeps no data on servers of ours, you can exercise these rights directly in the app: view it, edit it, export it to CSV —free, with no paid plan— or delete it. If you need further assistance, write to hola@sonanta.com.mx and we will respond within the periods set by law.

14Children

Sonanta is not directed to children and does not knowingly collect their data. If you are a parent or guardian and believe a child used the app, the data resides on the device itself and can be removed with "Erase all my data" or by uninstalling the app.

15Changes to this policy

We may update this policy to reflect changes in the app or in the law. The current version will always be at this address and inside the app, with its update date. If there are relevant changes, we will try to let you know inside the app.

16Contact

For any question about this policy or your privacy, write to hola@sonanta.com.mx.
