CodeStash is a lightweight promo-code manager for indie developers and small teams who need to organize review copies, launch giveaways, customer rewards, and other redemption codes without losing track of what was shared. If your codes currently live in App Store Connect downloads, spreadsheets, notes, chat messages, or one-off text files, CodeStash gives them one clear home. ONE POOL FOR EVERY CODE • Paste codes directly or import CSV and Excel files • Recognize code values and redemption links in App Store Connect exports • Preview imports and skip duplicates before saving • Organize by product, platform, campaign, benefit, and status • Track available, distributed, voided, expiring, and expired codes SHARE CODES WITHOUT LOSING THE THREAD • Distribute one code or select and share multiple codes at once • Record recipient, channel, notes, and campaign • Copy a code or redemption link when you are ready to share • Review import batches, distribution records, and the complete Code Ledger • Revoke batch distributions and restore deleted code records from the ledger UNDERSTAND YOUR CODE POOL • View overall distribution, seven-day trends, product totals, and campaign progress • Manage benefits, offer details, prices, and currencies • Edit previous import batches and add more codes • Export and restore encrypted CodeStash backup files • Optionally sync through your private iCloud database LIGHTWEIGHT AND PRIVATE BY DEFAULT CodeStash requires no account and includes no ads, subscriptions, or in-app purchases. Code data stays on your device by default. It only moves to a path you choose when you enable iCloud sync, export a backup, or use the system share sheet. CodeStash is not a CRM, email marketing service, or team SaaS dashboard. It focuses on one job: keeping redemption codes organized, traceable, and ready to share.
