Trade Sempai privacy policy
Effective date: 2026-11-04
This policy explains what information the Trade Sempai app and its online service collect, why, and the choices you have. Trade Sempai is provided by Trade Sempai ("we", "us"). Trade Sempai is a business management app for recording products, stock, sales, purchases, expenses and rentals.
Information we collect
Account information
- Your name and email address.
- Your password, which we store only as a one-way hash. We never see or store it in readable form.
- Your role in the business (for example owner, admin, manager, cashier, inventory officer or accountant) and which business you belong to.
- The name of the device you signed in from (for example "Tecno Pop 10"), so your active sign-ins can be managed and revoked.
Business information you enter
The app stores the information you and your team type into it, including:
- Business details and settings: business name, address, phone number, email, tax number (TPIN), currency, tax rate, document prefixes, receipt footer, time zone and your business logo.
- Products and services: names, prices, costs, stock quantities and stock history, stock adjustments and stock takes.
- Sales and receipts, including any customer details you add to a sale (such as a customer's name, phone number, email, address or tax number) and the payments recorded.
- Suppliers, purchase orders, goods received and supplier payments.
- Expenses, rentals (including the renter's contact details you enter), deposits and rental payments.
- Cash-register (POS) sessions: opening and counted cash, totals and closing notes.
Product photos you pick are kept on your device; only your business logo is uploaded to our servers. If you record information about your customers or suppliers, you are responsible for having a lawful reason to do so and for telling them how you use it.
Support messages
When you contact us from the app's Help page we receive your message and subject, your name, email, business and role, the app version and your device platform (for example Android), so we can reply and investigate the problem.
In-app notifications
We create notifications for you inside the app, such as low-stock alerts, cash differences when a register is closed, rental reminders, daily sales summaries and subscription reminders. These are built from your business data and stored with your account.
How we use information
- To provide the app: sign you in, keep your business data in sync across your team's devices, and produce receipts, documents and reports.
- To control access, so each team member can only do what their role allows.
- To send you in-app notifications and to answer support messages.
- To keep the service secure and working, and to prevent abuse.
We do not show ads, we do not sell your data, and we do not use third-party analytics or advertising trackers.
Where your data is stored
Your data is stored on our servers so it is backed up and shared with your team. A copy is also kept on each device you use, so the app keeps working offline and syncs when you are back online. Your sign-in token is kept in your device's secure storage. Signing out removes the sign-in token from that device.
Sharing
We do not share your information with third parties, except:
- With the members of your own business, according to their roles.
- With service providers that host and run our servers and email on our behalf, only as needed to provide the service.
- With Lenco when you choose to pay for a subscription or top-up on our website, only as needed to initiate, confirm and reconcile that payment.
- When required by law, or to protect the rights, safety and security of our users or the service.
Tutorial videos
Tutorial videos in the app are embedded from YouTube. When you play one, the video is delivered by YouTube (Google), which may collect information under the Google Privacy Policy. You do not need to watch the videos to use the app.
Payments
Sales payments you record in the app (cash, mobile money and so on) are business records. When a business owner buys a subscription or top-up on our website, we send Lenco the payment reference, amount, account email and, for mobile money, the phone number and selected operator. Card details are entered directly in Lenco's hosted payment window and are not received or stored by us. We keep the resulting payment status and provider reference so we can activate the purchase, prevent duplicates, provide support and maintain financial records.
Security
Data between the app and our servers is sent over encrypted HTTPS connections. Passwords are stored only as secure hashes, access to each business is limited to its members and their roles, and changing your password signs out your other devices. No method of storage or transmission is completely secure, but we work to protect your information.
How long we keep data
We keep your account and business data for as long as your account is active. When you delete your account it is removed from our servers as described below. Devices that were signed in to a deleted account or business erase their local copy the next time they connect; otherwise copies on your devices stay until you sign out, clear the app's data or uninstall the app.
So that those devices can be told what happened, we keep a one-way fingerprint (hash) of each deleted sign-in token, with whether the account or the business was deleted, for 180 days. It contains no name, email or business details.
Deleting your account
You can delete your account at any time in the app (Menu → Profile → My account → Delete account) or on the web at https://www.tradesempai.com/account/delete.
- If you are a business owner, deleting your account permanently deletes the whole business: all of its data, its logo and the accounts of all of its members, including their sign-ins, notifications, support messages and memberships of other businesses. A member who owns another business of their own keeps their account for that business and only loses access to the deleted one. Records a deleted member created in another business stay with that business without their name.
- If you are a staff member, only your own account is deleted. The records you created (such as sales) belong to the business and stay with it.
Deletion is permanent and cannot be undone. Phones and tablets signed in to a deleted account or business erase their local copy of its data the next time they connect to the internet.
Your rights
You can see and correct most of your information directly in the app, for example your name and email in My account, and your business details in Settings. You can also ask us for a copy of your information, ask us to correct or delete it, or object to how we use it, by contacting us below. Depending on where you live you may have further rights under local data-protection law, including the right to complain to your data protection authority.
Children
Trade Sempai is a tool for running a business. It is not directed at children under 13 and we do not knowingly collect information from them. If you believe a child has given us information, contact us and we will delete it.
Changes to this policy
We may update this policy from time to time. We will post the new version on this page and change the effective date above. If the changes are significant we will let you know in the app.
Contact
Questions about this policy or your information can be sent to Trade Sempai at [email protected] or through the Help page in the app.
