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

Business information you enter

The app stores the information you and your team type into it, including:

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

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:

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.

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.
