OSOB / support
HELP WITH OSOB.
OSOB — One Screen. One Battle. is in development by Dustoff Designs LLC and is not yet publicly available. This support draft covers the development build, previously called Duo Sports.
Need help or want to share feedback? Include your app version from Settings, device model, iOS or iPadOS version, and a short description of what happened and what you expected.
Prefer email? info@dustoffdesigns.com. The website form saves your message in our private inbox for manual review. Keep the request reference shown after submission. No response time is promised.
Quick fixes
- Close and reopen OSOB.
- Check that your device is running a compatible iOS version.
- Review sound, haptics, contrast and difficulty in Settings.
- If a match was interrupted, return to the arcade and start a new round.
The current release candidate shows bundled Dustoff Designs announcements rather than live network ads. In an advertising-enabled build, review advertising privacy choices in Settings when available in your region. If a network ad is unavailable, a bundled Dustoff Designs panel is used instead.
Report an advertisement
Tell us the date and approximate time, country, app version, placement and why the ad seemed inappropriate or misleading. If you already have a screenshot, remove personal information before attaching it. Do not tap an ad again just to collect information.
Or email an OSOB ad report. Dustoff Designs will review reports and work with the advertising provider when necessary. Do not send passwords, payment details or other sensitive personal information.
Purchases and receipts
Purchases are not enabled in the current development build. No payment is required, and earned Trophy Credits are not sold.
Open Settings → Purchases / Receipts, or Game Store → Purchases / Receipts. Apple issues the official payment receipt; use Apple purchase history for payment details and receipt help. OSOB does not issue Apple tax receipts or guarantee receipt emails.
When purchases are available, OSOB’s records show verified transactions for supported products, including the product, purchase date, transaction reference and verified or refunded/revoked status. Test records are labeled separately from real App Store purchases. Current store prices are not historical charged amounts.
For an eligible one-time unlock, use Restore Purchases with the Apple Account used to buy it. Restore does not recover earned Trophy Credits or local game progress. A pending purchase is not a completed purchase; wait for Apple’s approval rather than buying again. Cancelled or failed attempts do not unlock content, and refunded or revoked purchases may no longer provide access.
For help, share the product, app version and the displayed status through support. Do not send your Apple password, card details or an unredacted receipt. The website does not sell OSOB app unlocks.
Privacy and local progress
OSOB has no player account. Settings, earned Trophy Credits, achievements, match statistics, earned cosmetic ownership and selections, free-game mastery and solo bests stay on your device. Deleting the app removes local data, subject to your device’s normal backup and restoration behavior. Do not delete or reinstall the app as a first troubleshooting step if you want to preserve your progress.
Use the same support channel for a privacy question or a request about information you sent us. We do not have remote access to your on-device game progress. Read the OSOB privacy draft for the current development configuration and pending advertising decisions.
