This policy applies to Resistor Scanner and this policy page. It supplements the general Persie0 privacy policy; for this app, the more specific information on this page takes precedence.
Information used on your device
The app stores or processes the following information locally for the features you choose:
- camera/gallery resistor images and crops
- detected boxes, color bands and calculated resistance
- settings, scan history and submission identifier
Local processing is based on Art. 6(1)(b) GDPR where it is needed to provide a requested feature. Settings that are technically necessary are stored under the necessity exception in § 165(3) TKG 2021. Local information normally remains until you delete it, clear the app's data or remove the app.
Sharing successful scans is optional and remains disabled unless you consent to image sharing.
Permissions
Resistor Scanner may request these device permissions:
- Camera: scan a resistor.
- Photos/files: select images or save results.
- Network: ads, diagnostics, purchases and optional/training submissions.
Permissions can be changed in the operating-system settings. A feature that depends on a denied permission may then be unavailable.
Services and data transfers
The following services receive information only for the purposes described below.
Sentry (US, filtered)
Find and fix defects; protect stability and security. The information involved is: Crash and performance diagnostics, including the error and stack trace, app version, device and operating-system information, technical runtime data and the network IP address visible to Sentry. Common direct identifiers are filtered before transmission, although diagnostic text may still contain information entered or displayed in the app.
Recipient: Sentry; processing is hosted in the United States. Legal basis: Art. 6(1)(f) GDPR. You may object. Retention: 90 days in the configured Sentry project, then deletion; longer only for a concrete security/legal claim.
Advertising (Appodeal)
Display and measure advertising and prevent advertising fraud. Personalized advertising is used only with consent. The information involved is: Advertising ID where permitted, IP address, device and app information, ad impressions, clicks and fraud-prevention signals, and an approximate location inferred from the IP address.
Recipient: Appodeal and its advertising partners. Legal basis: Consent under Art. 6(1)(a) GDPR and § 165(3) TKG 2021 for non-essential device access. The choice can be changed in the app's privacy settings. Retention: The consent choice remains on the device until it is changed, reset or the app is removed. Appodeal and its partners apply the periods stated in their privacy information.
In-app purchases (RevenueCat)
Activate paid features, restore purchases, prevent fraud and provide support. The information involved is: Pseudonymous/anonymous app-user ID, product and entitlement identifiers, purchase/subscription status, store transaction metadata, app/device technical data and IP visible in network logs. Persie0 does not receive your payment-card details.
Recipient: RevenueCat and the selected app store. The store is a separate controller for payment. Legal basis: Art. 6(1)(b) GDPR (purchase/service) and Art. 6(1)(f) (fraud prevention and reliable entitlement state). Retention: For the subscription/purchase relationship and as needed to restore entitlements, resolve disputes and meet statutory accounting/claim periods; then deletion or de-identification.
Resistor training submissions
Build, validate and improve the resistor-detection dataset/model; prevent abusive uploads. The information involved is: Submitted full/cropped resistor image; YOLO-style bounding boxes; detected/calculated resistor value; submission ID (random UUID or value/email you configured); IP address, timestamp, rate-limit/allow status. The ID is hashed for storage-folder naming, but the backend currently also keeps the submitted ID/value and IP in an alias record.
Recipient: Persie0; hosting/infrastructure providers Vercel, MongoDB and MEGA. Legal basis: Consent under Art. 6(1)(a) GDPR for image and model-training submissions; Art. 6(1)(f) GDPR for rate limiting and service security. Retention: Rate-limit IP timestamps are deleted after about one hour. Alias records and submitted training files currently remain until the dataset purpose ends or you request erasure; irreversibly anonymized training derivatives/model weights may no longer be linkable to a submission.
This policy page
GitHub Pages receives the IP address, browser information, request time and requested page path to deliver and protect this page. Persie0 does not add analytics or advertising cookies to these policy pages. Processing is based on Art. 6(1)(f) GDPR; GitHub's infrastructure retention applies.
On-device AI
The app uses an on-device model for its local feature. Media remains on the device unless a separate transfer is described above. The output may be inaccurate and is not used by Persie0 for decisions with legal or similarly significant effects.
Processing outside the EEA
Some service providers may process information outside the European Economic Area. Where GDPR requires safeguards, processing relies on an adequacy decision, an applicable EU–US Data Privacy Framework certification, or Standard Contractual Clauses together with appropriate safeguards. You may request information about the applicable safeguard by email.
Deletion and retention
Local data can be removed through the app's delete or reset functions, by clearing app data, or by removing the app. Information held by a connected provider follows the period stated above and that provider's deletion process. Requests concerning data controlled by Persie0 can be sent to persie0@protonmail.com.
Your rights
Subject to the GDPR's conditions, you may request access, correction, deletion, restriction and portability; object to processing based on legitimate interests; and withdraw consent for future processing. You may also lodge a complaint with the Austrian Data Protection Authority.
Children
The app is not specifically directed at children. In Austria, consent for an information-society service can generally be given from age 14; below that age, parental authorization may be required. Provider-specific higher age limits described above continue to apply.
Changes and contact
This policy may change when the app or a connected service changes. The effective date appears at the top of the page. Questions and privacy requests can be sent to persie0@protonmail.com.
