Overview
Taza keeps most learning activity on your device. Core learning content works offline. Purchase verification, recording downloads and optional issue reports use online services. No Taza account is required to study.
Learning data and backups
Progress, streaks, quiz scores, flashcard history, settings, notes and custom text are normally stored locally on your device. They are not automatically uploaded to Taza as a learning profile. Device or operating-system backup features may also make copies under your device settings.
When you export a backup, you choose where to save or share a readable JSON file containing your learning data, including notes and custom text. Anyone with that file can read it. Temporary app-owned export files expire after 24 hours and are cleaned up the next time the app starts, returns to the foreground or exports another backup. Taza cannot delete copies you save or share elsewhere. Learning backups do not establish purchase ownership.
One-time Full Access purchase
Taza is free to download and offers a one-time purchase for Full Access, with no subscription or renewal. The applicable price is shown by your store. Apple or Google processes payment; Taza does not receive your full payment-card details.
RevenueCat receives an anonymous app user ID, purchase receipts, entitlement status and purchase history to verify and restore access, prevent purchase fraud and provide purchase-performance information. An anonymous purchase identifier does not require a Taza account.
Recordings and phone speech
When a recording is not already available on your device, Taza requests an existing recording using its filename. Taza's API, Cloudflare R2 and network providers process normal network metadata, such as IP addresses, to deliver and protect that request. App requests do not generate new audio through Google Cloud Text-to-Speech or ElevenLabs.
If a recording is unavailable, normal playback can use your phone's text-to-speech service. The selected voice and its availability depend on your operating system and device settings. Recording-only previews may instead show that the recording is unavailable.
Optional issue reports
If you choose to send a report, Taza receives your description, selected category, app version, source and any included question ID or question context. Reports are stored on Taza's server, and Resend may deliver a copy to the support mailbox. Reports can contain personal information if you enter it; avoid passwords, payment details, receipts and unnecessary personal information.
Historical access records
The former promo-code feature is retired. Historical redemption records may contain the code, redemption time and anonymous RevenueCat app user ID used to provide existing access and prevent abuse. Retiring that feature does not delete previously granted access.
Use of data and service providers
Online data is used to provide functionality, verify and restore purchases, respond to reports, understand purchase performance and protect the service. Taza does not sell personal information or use advertising trackers or cross-app advertising tracking.
The services involved include Apple, Google, RevenueCat, Cloudflare, Resend and Taza's hosting and database providers. Email you send to support is also processed by the relevant email providers. Their handling is governed by their own privacy terms and the applicable service arrangements.
Retention
Server-side issue reports older than 180 days from creation are deleted by a cleanup job that runs at server startup and daily. Unsent local reports expire after seven days and are removed when the report queue is processed.
Email copies, archives and provider backups follow the retention settings of the relevant mailbox or provider and may remain until those systems delete them. The server cleanup job does not delete these separate copies.
Purchase and historical redemption records are retained while needed to provide and restore access, prevent abuse, meet legal obligations and resolve support requests. Temporary API abuse history expires 48 hours after its applicable request window or ban ends. Hosting and other provider logs follow their configured retention settings.
Children's privacy
No account, name or email address is required to study. Optional reports and support messages may contain personal information supplied by the sender. If you believe a child has submitted personal information, contact support so the relevant records can be reviewed and deletion addressed.
Privacy requests
You may contact support@simpleengineer.org to ask about applicable access, correction or deletion rights. For a report, limited details such as the approximate submission time, reported lesson or question and a short non-sensitive excerpt can help locate it. For purchase support, include your anonymous Purchase Support ID from Settings when available. Do not send passwords, full payment details or store receipts by email.
Data not required for study
Taza does not require a login, name or email address to study. It does not request microphone, camera or precise-location access for learning, and it does not use advertising identifiers for tracking.
