Sign Documents (referred to in this document as "Sign Documents", "the app", "we", "us", or "our") is an iOS application for personal document signing. With Sign Documents you can open a PDF or a photo, place a saved signature or set of initials, and then export or share the signed file. This Privacy Policy explains what information we do and do not collect when you use the app, how that information is used, with whom it may be shared, and the rights and choices available to you.
We have built Sign Documents with a privacy-first posture. The documents you open and the signatures you create are processed and stored locally on your device. Sign Documents does not require you to create an account, sign up, or log in, and we do not operate a cloud sync service for your documents. By downloading, accessing, or using Sign Documents, you acknowledge that you have read and understood this Privacy Policy. If you do not agree with this Privacy Policy, please do not use the app.
To help explain things as clearly as possible in this Privacy Policy, every time any of these terms is referenced, they are strictly defined as:
We collect only the information described below. We have deliberately designed Sign Documents so that the most sensitive information you handle — your documents and your signatures — never leaves your device. The limited information we do collect is gathered automatically through third-party SDKs and falls into four categories: analytics and product usage, crash and diagnostic information, advertising and attribution data, and subscription-related data.
Sign Documents requires no account, sign-up, or login, and we do not ask you for your name, email address, postal address, or similar contact details in order to use the app. The documents you open and the signatures you create are not "provided to us" in any meaningful sense, because they are not transmitted to or accessible by us. If you contact us directly — for example, by emailing our support address — we will receive the information you choose to include in that communication (such as your email address and the contents of your message) so that we can respond to you.
When you use the app, certain information is collected automatically through third-party analytics tools, namely Google Firebase Analytics and Amplitude. This information helps us understand how the app is used so we can improve it. It may include:
Importantly, this analytics data describes how the app is used. It does not include the contents of your documents or your signatures.
To keep the app stable and to fix problems, we use Google Firebase Crashlytics to collect crash and diagnostic information. When the app crashes or encounters certain errors, we may automatically receive crash reports, stack traces, the state of the device and the app at the time of the crash, and related diagnostic information. This helps us identify and resolve bugs. Crash diagnostics do not include the contents of your documents or signatures.
To measure the performance of our marketing campaigns and to understand how new users discover the app, we use the Meta (Facebook) SDK, the TikTok Business SDK, and Google Ads On-Device Conversion measurement. These tools help us attribute app installs to specific campaigns and measure their effectiveness. They may access your device's Advertising Identifier (IDFA) and other identifiers, but only with your permission, as described in the section "Advertising, IDFA and App Tracking Transparency" below. Sign Documents is primarily funded by subscriptions; these advertising and attribution tools are used for marketing measurement rather than to serve in-app advertising.
This is one of the most important parts of this Privacy Policy, so we want to state it plainly: your documents and signatures stay on your device.
In short, the contents of your documents and signatures are private to you and are never collected by us.
We use the limited information we do collect for the following purposes:
We do not sell your personal information, and we have not done so. We do not trade your documents, your signatures, or your personal data to third parties for monetary or other valuable consideration. The third parties described in this Privacy Policy act as our service providers to deliver analytics, crash diagnostics, advertising attribution, and subscription management, and they process information only for those purposes and in accordance with their own privacy policies.
We rely on a small number of reputable third-party service providers to deliver analytics, crash reporting, advertising attribution, and subscription management. These providers process information on our behalf or in their own capacity in accordance with their respective privacy policies. We encourage you to review their policies:
We are not responsible for the privacy practices of these third parties, and your use of their services is governed by their own terms and privacy policies.
Sign Documents uses advertising and attribution SDKs (Meta, TikTok, and Google Ads On-Device Conversion) to measure marketing performance. On Apple devices, access to the Advertising Identifier (IDFA) and any tracking across apps and websites owned by other companies is controlled by Apple's App Tracking Transparency (ATT) framework.
The app will only access the IDFA or engage in cross-app tracking if you grant permission through the ATT prompt presented by the operating system. If you decline, the app will continue to function and we will not use the IDFA to track you across apps and websites owned by other companies. You can review or change your tracking preference at any time in your device settings under Privacy & Security, then Tracking. You can also enable "Limit Ad Tracking" or reset your Advertising Identifier from your device settings.
Sign Documents lets you sign your first 3 documents for free. To unlock unlimited signing and additional Premium features, you may purchase an auto-renewing subscription, available on a weekly, monthly, or yearly basis. All subscriptions and purchases are sold and processed through the Apple App Store.
Payment is handled entirely by Apple in accordance with Apple's terms and privacy policy. We never receive, process, or store your payment card numbers or other payment credentials. We use Adapty to help us manage subscription state and entitlements (for example, whether you currently have an active Premium subscription), but the underlying payment transaction is conducted by Apple. Subscriptions automatically renew unless auto-renewal is turned off at least 24 hours before the end of the current period; you can manage or cancel your subscription at any time through your Apple ID account settings.
Because your documents and signatures are stored locally on your device, they are retained for as long as you keep them on your device and you control their deletion — for example, by deleting individual documents or signatures within the app, or by deleting the app, which removes its locally stored data from your device.
Analytics, crash diagnostic, and attribution data processed by our third-party providers is retained in accordance with those providers' retention practices and our configured settings, and only for as long as reasonably necessary for the purposes described in this Privacy Policy or as required by applicable law. If you contact us by email, we retain that correspondence for as long as necessary to address your request and for our records.
We take reasonable and appropriate measures to protect information against loss, theft, misuse, and unauthorized access, disclosure, alteration, and destruction. Storing your documents and signatures locally on your device — rather than on remote servers — significantly reduces the exposure of that sensitive content. The security of data on your device also depends on the security of the device itself, including device passcodes, biometric locks, and operating-system protections. The data handled by our third-party providers is protected using the security measures those providers maintain. However, no method of transmission or electronic storage is completely secure, and we cannot guarantee absolute security.
We are based in Belarus, and our third-party service providers may process information in the United States and other countries. As a result, information collected through the app may be transferred to, stored in, and processed in countries other than the one in which you reside, where data protection laws may differ from those in your jurisdiction. Where required by applicable law, we and our service providers rely on appropriate safeguards for such international transfers. By using the app, you understand that your information may be transferred to and processed in such countries.
If you are located in the European Economic Area (EEA) or the United Kingdom, you have certain rights under the General Data Protection Regulation (GDPR) and the UK GDPR with respect to your personal data, including the right to access, rectify, erase, restrict, or object to the processing of your personal data, the right to data portability, and the right to withdraw consent where processing is based on consent. You also have the right to lodge a complaint with a supervisory authority.
The legal bases on which we rely to process personal data include: your consent (for example, for access to the IDFA and cross-app tracking via the ATT prompt, and for analytics where consent is required); our legitimate interests (for example, to understand and improve how the app is used, to keep the app stable through crash diagnostics, and to measure marketing performance), provided these interests are not overridden by your rights; and compliance with our legal obligations. To exercise your rights, please contact us using the details in the "Contact Us" section. Where processing is based on consent, you may withdraw that consent at any time, including by adjusting your tracking preferences in your device settings.
If you are a California resident, the California Consumer Privacy Act (CCPA) provides you with specific rights regarding your personal information, including the right to know what categories of personal information we collect and how we use it, the right to request access to or deletion of your personal information, and the right not to be discriminated against for exercising your privacy rights.
We do not sell your personal information. We have not sold, and do not sell, the personal information of our users, including California residents, in exchange for monetary or other valuable consideration.
Under the California Online Privacy Protection Act (CalOPPA), we also disclose how we respond to "Do Not Track" signals. The app does not currently respond to Do Not Track browser signals, as it is a native mobile application rather than a website; you can, however, control tracking through Apple's App Tracking Transparency framework and your device settings, as described above. To exercise your California privacy rights, please contact us using the details in the "Contact Us" section.
Sign Documents is intended for a general audience and is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and you believe that your child has provided us with personal information, please contact us so that we can take appropriate steps to delete such information. If we become aware that we have collected personal information from a child under 13 without verifiable parental consent, we will take steps to remove that information.
By using Sign Documents, you consent to our processing of information as described in this Privacy Policy. Where we rely on your consent — such as for access to the IDFA and cross-app tracking through Apple's App Tracking Transparency framework — we will obtain that consent before processing, and you may withdraw it at any time through your device settings.
We may update this Privacy Policy from time to time to reflect changes in our practices, our app, or applicable law. When we make changes, we will revise the "Updated at" date at the top of this document. We encourage you to review this Privacy Policy periodically to stay informed about how we handle information. Your continued use of the app after any changes become effective constitutes your acceptance of the revised Privacy Policy.
This Privacy Policy and any matters relating to it are governed by and construed in accordance with the laws of the Republic of Belarus, without regard to its conflict-of-law provisions, except where mandatory data-protection laws of your country of residence apply. By using the app, you agree to the application of the laws of Belarus to the extent permitted by applicable law.
