Privacy Policy

This English version is provided for reference purposes only. The Japanese version of this Policy shall prevail in all respects.

1. Basic Policy

A-Soft (“we”, “us” or “our”) respects the privacy of users of its iOS applications and official website. Our apps are designed so that data created by users is never sent to our servers.

2. Information Handling in Applications

The applications provided by us are not designed to collect or store personally identifiable information. Data you enter or create in the apps (such as notes, images or calculation data) is stored only on your device, and we neither obtain nor view it.

However, services provided by Apple, such as iCloud features or system crash reports, may transmit certain information based on the user’s device settings. Such information is managed in accordance with Apple’s privacy policy.

2-1. Location

In some apps (such as the note app A-Note), you can attach your current location to the data you create. Location data obtained this way is stored on your device and is never sent to us or to any third party. You can change or revoke the location permission at any time in iOS Settings > Privacy & Security > Location Services.

2-2. Photos and Camera

In apps that support attaching photos, images you select or take are copied into the app and stored there. Images are never sent to our servers. Access to the photo library and the camera can be changed at any time in iOS Settings.

2-3. Exchanging Data Between Apps on the Same Device

Some of our apps can exchange data with our other apps through a shared area on the same device, and only when you perform the corresponding operation. Such an exchange is completed on the device and does not go over a network.

2-4. Backup and Export Files

Backup and export files created by an app are saved to the destination you choose (the Files app, iCloud Drive, an email recipient and so on). Unless expressly stated otherwise, these files are not encrypted, and managing where they are stored and with whom they are shared is up to you.

2-5. Microphone

Apps that measure pitch (such as the guitar tuner K-Tuner) use the microphone to listen to your instrument and determine its pitch. Audio from the microphone is analyzed on the spot only; it is never stored as a recording and never sent to us or to any third party. You can change or revoke the microphone permission at any time in iOS Settings > Privacy & Security > Microphone.

2-6. Reading Receipts (Working with Your AI App)

In the calculator app A-CalcM, you can pass a photo of a receipt that you took or chose to an AI app of your choice (such as ChatGPT or Claude) through the iOS share sheet, then paste its answer to import the rows into a list. The photo is passed on your device directly to the AI app you choose; it does not go through our servers and we never receive it. Before you pass a photo for the first time, the app explains where it goes and how it is handled, and opens the share sheet only after you agree.

The photo and its contents are handled by the provider of the AI service you choose, under that service’s terms of use and privacy policy. Receipts include details such as the store name and the items and amounts you bought, so please make sure you are comfortable sharing them.

To import the AI’s answer, the app reads text from the clipboard. This text is used on the device only for the import and is never sent to us.

3. Communication from the Apps and Server Access Logs

Our apps may connect to our server (www.a-soft.info) to retrieve announcements and the list of our other apps. Such communication never transmits the data stored in the app, including notes and other entered content, images and location data.

As with any ordinary web server, connections are recorded in access logs containing the IP address, user agent, date and time, and the name of the file retrieved. We use these logs to investigate problems and to understand general usage, and not to identify individuals.

4. Information Received Through Inquiries

When you use the inquiry feature in an app, your mail app opens with the device model, OS version and app version filled into the message. A diagnostic log may also be attached in order to investigate a problem. Such a log contains records of operations, numbers of items processed and file names, but it does not contain note text, images or microphone audio themselves. If an app terminated unexpectedly, diagnostic data generated by iOS (such as the call stack at the time of termination) may also be attached; it likewise contains no user input or audio. You can review the message before sending it, and you may remove the attachment.

The email address and content we receive through an inquiry are used only to reply to you and to investigate the problem.

5. In-App Advertising

Some of our apps use the advertising SDK of a third-party ad provider, "Ad Generation" by Supership Inc., to display ads. In the course of ad delivery, the advertising identifier (only if you have allowed tracking) and certain device information may be transmitted to the provider. For details, please refer to the privacy policy of Supership Inc. (opens in a new tab) (Japanese).

In some apps, a dialog asking for permission to track may appear (for example, on first launch) under Apple's AppTrackingTransparency (ATT) framework. Even if you do not allow tracking, ads are still displayed, but the advertising identifier (IDFA) is not used for ad delivery and only non-personalized ads are served. You can change this permission at any time in iOS Settings > Privacy & Security > Tracking.

In apps where you have purchased the ad-removal in-app purchase, no ads are displayed and the advertising SDK transmits no information.

6. In-App Purchases

In-app purchases are processed through Apple’s App Store. We never receive payment information such as your name, address or credit card number. Whether a purchase has been made is determined on the device, based on the purchase information provided by Apple.

7. Disclosure to Third Parties

We do not provide information about users to third parties, except as described in this Policy or as required by law.

8. Children’s Privacy

Our apps are not directed at children, and we do not knowingly collect personal information from children.

9. Official Website

Some older pages of this website (help and information pages opened from earlier versions of our apps) use Google Analytics for access analysis. Google Analytics uses cookies to measure how pages are viewed; we receive only aggregated data that does not identify individual users. The collected information is handled under Google’s Privacy Policy (opens in a new tab).

Some pages also show short videos (YouTube) that introduce our apps. The video player is loaded only when you tap a thumbnail to play a video; simply opening a page does not connect to YouTube (the thumbnail images are hosted on this website). The player is loaded in YouTube’s privacy-enhanced mode (youtube-nocookie.com), but once you play a video, information about your viewing may be sent to YouTube (Google), and cookies or similar technologies may be used. We do not receive this information; it is handled under Google’s Privacy Policy (opens in a new tab).

10. Changes to This Policy

We may change the contents of this Policy. If we do, we will post the updated Policy on this page and update the last-updated date shown below.
