This Privacy Policy explains how WoilaTech (Pont Norvégien, Marché
Bantaï, Ngaoundéré, Cameroon) collects, uses and protects the personal data processed by
Lisafi Pro: the Android app (com.woilatech.lisafipro) and the
web app, on computers, tablets and phones. By using Lisafi Pro you agree to the practices
described below.
1. Who controls your data
- You, the shop user (owner or manager), and the distributors of the partner program: WoilaTech is the data controller for your account data.
- Your shop's data — your customers (name, phone, balance), your sales, your catalogue, your expenses: you, the merchant, are the controller. WoilaTech acts only as a technical processor hosting and processing it on your behalf. It is your responsibility to inform your customers and obtain their consent to store their data and send them reminders (see our Terms of Service).
2. Data we collect
| Category | Data |
|---|---|
| Account & sign-in | Phone number (SMS-code sign-in), email address (email/password sign-in), Google account name and email (Google sign-in), display name, role in the shop. |
| Shop | Shop name, city, address, phone and WhatsApp numbers, Mobile Money number, activation code used, Lisafi Pro subscription status. |
| Team | Name and phone of each manager the owner adds, and the rights granted to them. |
| Customers and credit ledger | Customer name and phone, running balance, dated entries ("took goods", "paid", amount, note), date of the last reminder. |
| Catalogue and stock | Products (name, reference, category, purchase and sale price, quantity), optional product photo (compressed), dated stock movements, categories, CSV files you import. |
| Sales | Sale lines, amounts, discounts, payment method (cash, Mobile Money, credit), customer if any, seller, receipt number, cancellation and its reason. |
| Expenses | Amount, category, date and note of each recorded expense. |
| Activity log | Who did what and when in the shop (sale, ledger entry, change), so the owner can follow their team. |
| Payments | Mobile Money number and pawaPay deposit records for the Lisafi Pro subscription (MTN, Orange). Lisafi Pro never sees or stores a Mobile Money PIN. |
| Support | Support requests and the messages exchanged with WoilaTech or with your shop's distributor. |
| Distributor program | For distributors only: name, phone, city, application note, distributor code, shops installed, commissions, monthly statements and payouts. |
| Device & technical | Push notification token (FCM, Android); the screen-lock code, kept only on the device in hashed form and never sent; preferences (language, theme, chosen shop, printer) stored locally. |
Android app permissions
- Internet: sync the shop with our servers.
- Notifications: tell you about sales, ledger entries and support messages. You may refuse them.
- Bluetooth: print receipts on a thermal printer you choose. Lisafi Pro does not use it to locate you.
- Camera / gallery: only when you add a photo to a product.
Lisafi Pro does not collect your location, does not read your contacts, shows no advertising and does not track you for advertising purposes.
3. How we use this data
- Keep the shop's catalogue, stock, sales and expenses;
- Print, download or share receipts;
- Keep the credit ledger shared with Lisafi and show who to follow up;
- Open a WhatsApp reminder for a customer, at your request;
- Compute the shop's dashboard, finances and profit;
- Manage team rights and the activity log;
- Process the Lisafi Pro subscription and activation codes;
- Run the distributor program (installations, commissions, payouts);
- Send notifications and answer support requests;
- Keep the service secure and prevent fraud.
4. Who can see a shop's data
- The shop's members, each within the rights the owner gives them.
- The distributor who installed the shop: they see what they need to activate and follow it (name, contact, subscription status) and that shop's support requests — not its customers, sales or stock.
- WoilaTech's administration team, for support, billing and security.
No shop can see another shop's data.
5. Sharing with third parties
We never sell your data. We rely on technical providers:
- Google Firebase (authentication, Firestore database, photo storage, notifications, server functions, web hosting) — hosted on Google Cloud. Firebase policy / Google Privacy.
- Google Sign-In, when you choose that sign-in method.
- pawaPay — Mobile Money payments (MTN, Orange). pawaPay policy.
- Google Fonts — the web app's fonts are loaded from Google's servers, which receive your IP address.
- WhatsApp and share targets — a reminder or a receipt opens in the app you choose and is then governed by that app's policy.
We may also disclose data where the law requires it.
6. International transfer
Google Firebase services may store and process data on servers located outside Cameroon. By using Lisafi Pro you consent to this transfer, which is covered by these providers' contractual safeguards.
7. Retention and deletion
Data is kept as long as your account and shop exist. Sales, ledger entries and the activity log cannot be edited: a mistake is corrected by a new line, which keeps the history trustworthy in a dispute. Deleting the account erases the shop's data — customers, ledger, catalogue, photos, stock, sales and expenses (see Account & Data Deletion). Payment, commission and billing records may be kept for as long as accounting law requires.
8. Security
- Each shop is isolated by access rules enforced on the server;
- data travels encrypted (HTTPS / TLS);
- the subscription and commissions are confirmed only on the server, after a real payment: the app can never unlock itself;
- each member has only the rights the owner gives them;
- a screen-lock code and "sign out of all devices" are available.
No system is infallible: we cannot guarantee absolute security.
9. Minors
Lisafi Pro is meant for merchants and is not intended for minors. You must be at least 18 years old to create an account.
10. Your rights
You can view and correct your data directly in Lisafi Pro, ask for a copy of your data, and delete your account from the Profile screen or by writing to techwoila@gmail.com.
11. Changes
We may update this policy. The "Last updated" date shows the version in force; significant changes will be announced in the app.
