Terms of Service
By using Transposo you agree to these terms, which cover the free version, the Pro subscription and the photo scanning feature.
1. What Transposo does
Transposo rewrites notes from one instrument's key to another and draws the result as sheet music. You can type the notes with the in-app keypad or scan a photo of printed music.
2. Check the music yourself
Transposition is calculated by the app, and scanned notes are read by an AI model that can misread a note, a rhythm or a time signature. Always review the notes in the input field before you rely on a result, and check the final sheet before performing from it. We cannot guarantee that any result is complete or correct.
3. Free version and Pro
| Free | Pro | |
|---|---|---|
| Transposing and sheet view | Yes | Yes |
| AI photo scans | 2 per day, plus one extra for each rewarded ad you watch | No daily limit |
| Ads | Banner, and an interstitial every third transposition | None |
| PDF and image exports | Carry a "Created with Transposo Free" line | No line |
We may change these limits for the free version in a future update, and we will show the current limits in the app.
4. Subscriptions
Pro is sold as a monthly or a yearly subscription. The price and billing period are shown in the app before you buy, in your local currency.
- Payment is charged to your Google Play or Apple App Store account when you confirm the purchase.
- The subscription renews automatically at the same price and period unless you cancel at least 24 hours before the end of the current period.
- You manage and cancel it in your store account settings, not inside Transposo. Deleting the app does not cancel it.
- Refunds are decided by Google or Apple under their own rules.
- If you reinstall the app or change phone, use Restore purchases in the paywall to get Pro back.
5. Using the scanning feature
Scan only music you are allowed to copy. Sheet music is often protected by copyright, and you are responsible for having the right to scan the pages you submit. Do not submit photos that are unlawful, that show other people, or that contain personal information. Do not try to misuse, overload or reverse engineer the scanning service.
6. Your content and our rights
The notes you enter and the sheets you create stay yours. The app, its design and its code belong to Ege Arca Tunç, and you may use them only as these terms allow. You may not copy, resell or reverse engineer the app.
7. Availability
Scanning, ads and purchases depend on services run by Google, Cloudflare, RevenueCat and the app stores. They can be slow, change or be unavailable, and we are not responsible for that. Transposing and the sheet view work without an internet connection.
8. No warranty and limit of liability
Transposo is provided as is, without promises that it is error free or always available. To the extent the law allows, Ege Arca Tunç is not liable for indirect or consequential loss, or for loss caused by relying on a transposition or a scan. Nothing in these terms limits rights you have under mandatory consumer law.
9. Ending use
You can stop using Transposo at any time by cancelling your subscription and uninstalling the app. We may suspend access for misuse of the scanning service.
10. Apple devices
On iOS, Apple's Standard Licensed Application End User License Agreement also applies. Apple is not responsible for the app or its support.
11. Changes and law
We may update these terms and will change the date at the top; continuing to use the app after a change means you accept it. These terms are governed by the laws of Turkey, without removing any consumer protection that applies where you live.
