Privacy Policy
Last updated: November 2026
Introduction
Asymmetric Enterprises ("we," "our," or "us") values your privacy. This Privacy Policy explains how we handle data for all iOS applications ("Apps") developed and released by us, including UnitLens and Subnet Vault, and our related website and services. By using our Apps, you agree to the terms described in this policy.
1. Information We Collect and Do Not Collect
We do not collect personal information, identifiable data, or individual usage data directly through our Apps. Any data entered or generated in our Apps remains on your device and is under your control. The exception is information you choose to send us, such as a diagnostic report or a support message, as described in Section 6.
However, certain features within our Apps rely on third-party services that may collect limited data, as described in this policy. UnitLens looks up products in the Open Food Facts and Open Beauty Facts databases, and its product details include links to online retailers. Links to Amazon.com are affiliate links under the Amazon Services LLC Associates Program. Following any store link takes you to that retailer's website, which may collect data as described in Sections 3 and 5 below. Subnet Vault's network tools send the host names and addresses you look up to public internet services in order to answer them, as described in Subnet Vault Network Tools in Section 5. Econ Core downloads published economic data from public data providers, as described in Section 5.
2. Website Analytics
Our website (asymmetric.enterprises) uses Google Analytics to collect anonymous information about website traffic and user behavior. This applies only to our website and not to our mobile applications or audio content. The website analytics data includes:
- Pages visited and time spent on each page
- Type of browser and device used
- Referring website or source
- General geographic location (city/country level)
- Anonymous usage patterns
This data is collected using cookies and similar technologies, and is used solely to improve our website's content and user experience. No personally identifiable information is collected through Google Analytics, and this data is not combined with any app-related data.
3. Affiliate Program Participation and Cookies
UnitLens includes links that help you find a product at online retailers.
Amazon Associates Program.UnitLens is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites and applications to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate, we earn from qualifying purchases. The "Find this product" section of a product's details includes a link that searches Amazon.com for that product, and this link carries our Associates tag. When you follow it, Amazon may place or recognize cookies on your browser or device to determine whether a qualifying purchase occurs during the session that begins with your click. Amazon may monitor, record, use, and disclose information obtained in connection with your use of the link and any resulting interactions with Amazon.com. We do not collect, store, cache, or otherwise use any account information of Amazon customers.
Other Store Links. In the United States, UnitLens also shows links that search Walmart.com and Kroger.com for the product. These are ordinary links without affiliate tags, and we earn nothing from them. Like any website you visit, Walmart and Kroger may place cookies on your browser and collect data under their own privacy notices.
Price Comparisons. UnitLens includes an optional price-comparison feature that is currently turned off. If it is turned on, UnitLens would send a product's name, brand, or barcode to the Amazon Product Advertising API and the Walmart Affiliate API to retrieve current prices, and links to Walmart may then be affiliate links administered through Impact Radius (impact.com) under the Walmart Affiliate Program. We will update this policy before turning this feature on.
Cookies and Tracking Technologies. When you follow a store link from UnitLens, the retailer and, for affiliate links, its affiliate network may place or recognize cookies on your browser or device to track referral activity, attribute qualifying purchases, and calculate commissions. This happens in your browser, outside UnitLens. The app itself places no cookies and does not track you across apps or websites.
Data Collected by Third Parties.We do not receive or store your purchase information, payment details, or retailer account information. Amazon, Walmart, Kroger, and their service providers may collect data about your visit after you follow a link, including products viewed and purchased. That data is governed by each retailer's privacy notice: Amazon's Privacy Notice (amazon.com/gp/help/customer/display.html?nodeId=468496), Walmart's Privacy Notice and Kroger's Privacy Policy (each linked in the footer of the retailer's website), and, for any Walmart affiliate links, Impact.com's privacy policy.
Your Consent and Choices. By following a store link from UnitLens, you consent to the placement of cookies and the collection of data by that retailer and, for affiliate links, its affiliate network, as described above. You can block or delete cookies in your browser or device settings; doing so may affect the retailer's website, including its ability to attribute qualifying purchases.
4. Data Storage and Cloud Syncing
Some of our Apps may store data locally on your device or sync it using Apple iCloud through CloudKit. Our audio content is streamed and may be temporarily cached on your device.
- Local Storage: Data entered into our Apps remains on your device.
- iCloud Syncing: If enabled, data is encrypted and synced via Apple's iCloud services, which are subject to Apple's privacy and security policies.
- Audio Content: Our podcasts and audio content are streamed through third-party podcast platforms (Apple Podcasts, Spotify, etc.) and are subject to their respective privacy policies.
- Our Access: We do not have access to your iCloud data or podcast listening history.
5. Third-Party Services
Our Apps and website interact with the following third-party services:
- Amazon.com: UnitLens participates in the Amazon Services LLC Associates Program. Its Amazon store link carries our Associates tag, and Amazon may place cookies on your browser or device to track referral activity and purchases. Amazon's Privacy Notice governs the data Amazon collects.
- Walmart and Kroger: In the United States, UnitLens links to product searches on Walmart.com and Kroger.com. These links are not affiliate links, and each retailer's privacy notice governs data it collects when you visit. If price comparisons are turned on (see Section 3), Walmart prices come from the Walmart Affiliate API and Walmart links may be affiliate links administered by Impact Radius (impact.com), governed by Walmart's Privacy Notice and Impact.com's privacy policy.
- Open Food Facts and Open Beauty Facts: UnitLens retrieves product, nutrition, ingredient, and allergen information from Open Food Facts and its sister project Open Beauty Facts, free and collaborative open databases run by the non-profit Open Food Facts association. A lookup sends only the barcode you scan or enter, or the words you search for, together with the app's name, its version, and our support email address so the projects can identify where requests come from. Like any web request, it also reveals your device's IP address. Product images are loaded from the same projects. Your allergen and diet settings are applied on your device and are never sent. Open Food Facts' privacy policy governs any data they collect.
- Subnet Vault network services: Subnet Vault's network tools query public internet services such as ipify, Measurement Lab, Globalping and DNS over HTTPS resolvers. Each service, and what is sent to it, is listed in Subnet Vault Network Tools below.
- Econ Core data sources: Econ Core downloads published economic data directly from Federal Reserve Economic Data (FRED, run by the Federal Reserve Bank of St. Louis), the U.S. Treasury's Fiscal Data service, the World Bank, Eurostat, DBnomics, the International Monetary Fund, and CoinGecko. We operate none of these services, and we never see the requests or the results. A request names the indicator or release schedule and the period of data the app needs, and identifies the app by name; requests to FRED also carry an access key that belongs to the app rather than to you. We add no account, advertising, or device identifiers to any request. Each request necessarily reveals your device's public IP address to the service that answers it, exactly as visiting any website does. Requests are made when you open the app or an indicator, when you pull down to refresh, and when iOS allows a background refresh, which covers only the indicators on your list. Your list, followed releases, and saved data are stored only on your device and are not synced through iCloud. Release alerts are scheduled by the app on your device and are not sent through any server. Econ Core contains no analytics, advertising, or third-party SDKs and does not track you across apps or websites. Each provider's own privacy policy governs any data it collects.
- Google Analytics: Our website uses Google Analytics to track anonymous website usage patterns, as described in Section 2. Google's Privacy Policy applies to this data collection.
- Resend: Our website uses Resend to process contact form submissions and newsletter subscriptions. When you submit the contact form or subscribe to our newsletter, your email address and message are transmitted to Resend for delivery. Resend's Privacy Policy governs this data processing.
- Apple App Store Badges: Our website displays App Store badges hosted by Apple to link to our applications. These badges may load resources from Apple's servers (tools.applemediaservices.com).
- Podcast Platforms: Our audio content is distributed through third-party podcast platforms including Apple Podcasts, Spotify, Amazon Music, and iHeartRadio. When you access our podcasts through these platforms, their respective privacy policies apply to any listening data or analytics they collect.
- Apple iCloud: Some Apps use Apple's iCloud and CloudKit services for data syncing across your devices. All data synced through iCloud is subject to Apple's Privacy Policy and is encrypted in transit and at rest.
- Apple MetricKit: Some Apps use Apple's MetricKit framework, through which iOS gives the app on your device reports about its performance, such as battery and CPU use, hangs, and crashes. These reports stay on your device unless you choose to send them to us, as described in Section 6.
We do not control these third-party services and recommend reviewing their privacy policies to understand how they handle your information.
Subnet Vault Network Tools
Subnet Vault is a networking utility. Several of its tools work by sending a request to a public internet service and showing you the reply. We operate none of these services, we add no account, advertising or device identifiers to any request, and we never see the requests or the results. Each request necessarily reveals your device's public IP address to the service that answers it, exactly as visiting any website does. Where a tool sends more than that, it is listed below.
Runs automatically when you open a tool
- Public IP address (My Network tool): ipify (api.ipify.org and api64.ipify.org). The request carries no data; the reply is your public IPv4 and IPv6 address, shown on screen. Privacy policy: ipify.org.
Runs only when you start a test or look something up
- Speed Test: Measurement Lab (M-Lab) NDT7 servers, located through locate.measurementlab.net. Before the first test the app asks for your consent and explains that M-Lab publishes every test's IP address, time and results as open data. You can withdraw consent in the tool at any time. Privacy policy: measurementlab.net/privacy.
- Worldwide Ping, Traceroute, DNS and HTTP checks: Globalping (api.globalping.io), which runs the measurement from probes around the world. The request contains only the public host name or address you typed. The app refuses private and local addresses. Privacy policy: globalping.io.
- IP geolocation: ipwho.is, with ipapi.co as a fallback. The request contains the IP address you typed, or your own public address if you leave the field empty.
- WHOIS and RDAP lookups: the IANA WHOIS server (whois.iana.org), the IANA RDAP bootstrap file (data.iana.org), and the regional and domain registries it directs the app to, such as ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC and Verisign. The request contains the domain or address you typed.
- DNS lookups and DNS propagation checks: DNS over HTTPS resolvers run by Cloudflare (cloudflare-dns.com) and Google (dns.google), and for propagation checks also AdGuard (unfiltered.adguard-dns.com) and Alibaba AliDNS (dns.alidns.com). The request contains the domain name you typed.
- Network operator (ASN) names on traceroute hops: Team Cymru's IP-to-ASN service (origin.asn.cymru.com), queried over DNS over HTTPS. This is off by default; when you turn it on, each hop's public IP address is sent.
- NAT type detection (My Network tool): STUN servers run by Cloudflare (stun.cloudflare.com) and Google (stun.l.google.com). The request carries no data; the reply tells the app how your router maps addresses.
Stays on your device
- Subnet calculations, VLSM plans, the OSI Model page, MAC address vendor lookup (a bundled copy of the IEEE registry), Bluetooth and NFC scanning, local network scanning, Bonjour browsing and Wake-on-LAN exchange data only with devices on your own network and send nothing to the internet.
- Saved results are stored on your device and, if iCloud is enabled, in your own iCloud key-value store under Apple's privacy policy. We cannot read them.
Subnet Vault contains no analytics, advertising or third-party SDKs and does not track you across apps or websites.
6. App Analytics and Diagnostics
We may access aggregate and anonymous analytics data provided by Apple through services like App Store Connect. This data includes general trends and insights but does not contain any personal or identifiable information. Examples of such data include:
- Total app downloads
- General usage metrics, for example session length and active user count
- Crash reports
Some of our Apps also use Apple's MetricKit framework, through which iOS gives the app on your device daily reports about its performance, such as launch times, battery and CPU use, memory use, hangs, and crash diagnostics. These reports are created and kept on your device, and our Apps never send them to us automatically.
Diagnostic Information You Choose to Send. Several of our Apps let you send us diagnostic information to help us fix a problem, through an option such as Report a Bug, Report an Issue, Export Diagnostics, or Share diagnostics. Nothing is sent until you choose to send it, and you choose how it is sent, for example by email. Depending on the App, a report may include performance and crash reports, recent app log entries and errors, the App's version and settings, and your device model and operating system version. Each App's user guide describes what its reports contain, and some Apps let you preview a report before you send it. If you send a report by email, we also receive your email address and anything you write. We use this information only to investigate and respond to the problem you report, and we never sell it or use it for advertising.
This information helps us improve app performance and the user experience.
7. FTC Disclosure and Affiliate Relationships
In accordance with the Federal Trade Commission's Guidelines on Endorsements and Testimonials, we disclose the following affiliate relationships:
Walmart Affiliate Program.UnitLens's links to Walmart are not currently affiliate links. If price comparisons are turned on (see Section 3), Walmart links may become affiliate links, and we may then earn a commission on qualifying purchases at no additional cost to you.
Amazon Associates Program. UnitLens is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites and applications to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate, we earn from qualifying purchases.
These affiliate relationships do not influence the product information, nutrition data, or food quality scores displayed within UnitLens, which are sourced from the Open Food Facts and Open Beauty Facts databases.
8. Confidential Information
In connection with our participation in the Amazon Associates Program and, where applicable, the Walmart Affiliate Program and the Impact Radius platform, we may receive certain confidential business information from Amazon, Walmart, and/or Impact Radius. We treat all such information as confidential in accordance with our contractual obligations and do not disclose it to third parties except as required by law or as authorized by the disclosing party.
9. Amazon Product Advertising Content Disclaimer
If UnitLens shows content from Amazon, such as product prices when price comparisons are turned on, that content is provided "as is" and is subject to change or removal at any time. Product prices and availability are accurate as of the date and time indicated and are subject to change. Any price and availability information displayed on Amazon.com at the time of purchase will apply to the purchase of the product.
10. Your Data Rights
Apart from diagnostic reports and messages you choose to send us, we do not store or manage user data outside of your device or iCloud. If you wish to manage or delete your data:
- Use the App's settings to reset or clear data stored locally.
- Manage your iCloud data through your Apple Account settings on your device.
- To ask us to delete a diagnostic report or message you have sent us, email support@asymmetric.enterprises.
- To manage cookies placed by retailers or affiliate networks you visit from our Apps, adjust your browser or device cookie settings.
11. Children's Privacy
Our Apps are not directed toward children and are not intended for children under the age of 13 (or the minimum age required in your jurisdiction). We do not knowingly collect, use, or disclose personal information from children under 13. In accordance with the Children's Online Privacy Protection Act (COPPA) and applicable child protection laws, if we become aware that personal information has been inadvertently collected from a child under 13, we will take steps to delete such information promptly.
12. Data Protection and International Users
If you access our Apps or services from outside the United States, please be aware that data may be transferred to, stored, and processed in the United States or other jurisdictions where our third-party service providers (including the retailers and data services described in Section 5) operate. By using our Apps, you consent to such transfers. We comply with applicable data protection laws, including the General Data Protection Regulation (GDPR) where applicable, and the California Consumer Privacy Act (CCPA).
13. Business Transfers
In the event that Asymmetric Enterprises, or substantially all of its assets, is acquired by, merged with, or transferred to another entity — whether through a sale, merger, reorganization, dissolution, or similar transaction — any data associated with our Apps and services (including aggregate analytics data, app listings, user reviews, and any data synced through third-party services such as iCloud) may be transferred to the successor entity as part of that transaction. Because we do not collect or store personal information directly, any such transfer would primarily involve aggregate, anonymized data and operational assets rather than individually identifiable user data. The successor entity would be bound by the terms of this Privacy Policy with respect to any data transferred, until such time as an updated policy is published. If a business transfer were to result in a material change to how data is handled, we would notify users by updating this Privacy Policy and revising the "Last Updated" date.
14. Changes to This Policy
We may update this Privacy Policy occasionally to reflect changes to our practices, the addition of new third-party integrations, or legal requirements. Updates will be posted here, and the "Last Updated" date will be revised accordingly. We encourage you to review this policy periodically. Your continued use of our Apps after any changes to this Privacy Policy constitutes your acceptance of such changes.
