OVERVIEW
Sign Run does not require an account, and we do not sell personal information. You open a PDF, place your signature, initials, dates, text and check marks on it, and create a new signed PDF. Your documents and saved signatures are kept in the app's storage on your device. The app also uses Google services and an advertising mediation partner for analytics, crash reporting, remote configuration, and advertising.
DOCUMENTS, SIGNATURES AND CAMERA
When you tap "Open PDF", the system file picker opens and only the PDF you choose is given to the app. The app keeps its own copy of that PDF in its storage. Your original file is not changed; exporting creates a new PDF.
You can create a signature or initials by drawing, by typing (the text is drawn as an image in a chosen style), or from a photo of your ink signature. "Import photo" opens the system photo picker, and only the photo you choose is given to the app. The camera is used only when you choose "Photo of my signature" while creating a signature or initials (in the signature library or from a document); Android asks for camera access at that point. If you decline, the app shows that access was not granted and you can still draw, type or import a photo. Photos are processed on your device into an image cropped to the ink, and the app keeps a signature image in its library only when you tap Save. Temporary copies made by the system pickers and the camera, and temporary images made while you create a signature, may remain in the app's cache. Documents, signatures and photos are processed on your device; the app does not upload them.
INFORMATION STORED ON YOUR DEVICE
For each document the app keeps its copy of the PDF, its name and size, page layout information, and your list of places to fill: their page and position, type (signature, initials, date, text, check box or option), status, whether they are required, form field names and labels from the PDF, which saved signature is used, and the text or date you entered. The app also keeps a preview copy, a thumbnail and page images of documents in its cache. For each saved signature or initials it keeps the image, its name, type and size. The app also keeps a list of IDs of deleted items so that restoring an older backup does not bring them back; this list is kept without a limit.
The app may also store basic operating information such as cached advertising settings and a cached More Apps list. If a saved record cannot be read, the app leaves it untouched and shows that it could not be read.
The developer does not run a server that receives your documents or signatures. The app reads developer-controlled advertising settings and a More Apps list from Google Cloud Firestore, but it does not upload your PDFs, signatures or the values you enter. When you open the developer's other apps in the menu, app icons are loaded from the web addresses in that list.
ANALYTICS, CRASH REPORTING, AND ADS
Google Firebase Analytics may process limited app-usage and technical information, such as app launches, a screen view when the app starts, tapping the review item in the menu, opening the More Apps list, whether a review request from the menu or the exit dialog was attempted, unavailable or failed, ad revenue events (ad format, value, currency and precision), app version, device type, and app-instance identifiers. These events do not include document names, signature images, or the text and dates you enter.
Google Firebase Crashlytics may process crash reports and related technical information needed to diagnose app problems.
The app shows ads through Google AdMob. A banner may appear at the bottom of the home screen, and an ad may appear in the exit dialog. Full-screen ads may appear when the app opens or returns to the foreground, and occasionally after you finish an export and tap Done. The app does not start a full-screen ad while a document, the signature library, the backup screen or the export screen is open. AdMob may also request ads from the InMobi mediation network. Google and InMobi may process advertising identifiers and device, app, consent, network, and ad-performance information to provide and measure ads, and may use an IP address to estimate an approximate location even though the app has no location permission.
PERMISSIONS AND ADVERTISING CHOICES
The only feature permission the app requests is the camera, as described above. It does not request microphone, location, contacts, Bluetooth, health data, or notifications. It also uses internet access and the Android advertising ID permission for the services above, and vibration for short haptic feedback.
When the app starts, Google's consent message (UMP) is checked first. Where consent is required (for example in the EEA and UK), personalized advertising stays off unless your choice allows it, and if the consent result does not allow ad requests, the app does not request ads. If the consent message cannot be loaded, the app still requests non-personalized ads, personalized advertising stays off, and "Privacy choices" is not shown until the app is started again. Where Google requires it, the app's menu shows "Privacy choices", which reopens the consent message so you can change your advertising choice. The app works whatever you choose.
STORAGE AND YOUR CONTROL
You can delete a document with "Delete" under it on the home screen, and delete a saved signature or initials in the signature library. A signature cannot be deleted while a saved document uses it. After you delete, "Undo" is available for a short time (about 8 seconds, or until you delete another item). Deleting moves the item's saved files to a holding folder in the app's storage so that Undo can bring them back, and removes backup files the app holds that include the item; deleting a document also removes its preview, thumbnail and signed PDFs in the app's cache. The held files are removed when the undo period ends or the next time the app starts. You can also clear the app's data in Android settings or delete the app. Local data may be included in a Google or device backup depending on your backup settings; uninstalling normally removes the active copy but may not remove an older backup.
Signed PDFs are written to the app's cache. "Share" sends the file through the system share sheet, and "Save to folder" copies it to a folder you pick; the app does not delete copies kept elsewhere. "Create backup" in "Backup and restore" writes a set of files with your documents (including the PDFs and the values you entered), your saved signatures and the deleted-ID list to the app's cache (if a saved record cannot be read or a file is missing, the app does not create the backup); you can share each file or save the set to a folder you pick. When the app next starts, it deletes the signed PDFs and backup files in this cache folder (a file that cannot be removed at that moment is kept). "Restore backup" reads backup files you pick; the app keeps the backup parts you selected in its storage so that missing parts can be added later, and removes them once that backup has been fully applied. Temporary copies of backup files from the file picker may remain in the app's cache.
Because we do not receive your documents or signatures, we cannot delete them for you; the controls above remove them from the app. For questions about data processed by Google or InMobi, or to ask us for help with a privacy request, contact us at the address below.
Data processed by third parties is retained according to their service settings and policies. We use these services under their applicable terms, and we ensure that third-party service providers with whom we share user data provide the same or equal protection of that data as stated in this policy.

SECURITY
Your documents, signatures and backup files are kept in the app's private storage on your device, which the operating system protects from other apps; they are not separately encrypted by the app, so protect your device with a screen lock. Apart from the limited analytics events described above, the app does not upload your saved data. Communication between the app and Google services and the ad mediation partner uses encrypted connections (HTTPS/TLS). No method of storage or transmission is completely secure, but we limit what the app collects to what is described in this policy.
IMPORTANT NOTICE
Sign Run places images of your signature and the values you enter onto a new PDF. It does not create certificate-based digital signatures, verify anyone's identity, or determine whether a signed document is legally valid. Suggested places come from the PDF's form fields and may be incomplete, so review the signed PDF before you send it. Only sign documents you are entitled to sign.
CHILDREN
The app is not directed to children under 13, and we do not knowingly collect personal information from children.
CHANGES
We may update this policy if the app or its services change. The date above shows the latest revision.
