Nixo · Effective November 10, 2026
In short
Nixo (“the app”) is made by Dmytro Podhorets, an independent developer (“we”, “us”). We are responsible for your data under this policy (the “controller” under the EU and UK GDPR). Contact: support@nixo.photos.
With your permission, the app reads your photo library to show your photos, group shots taken seconds apart, and help you choose what to delete. It also reads the date, size and location stored in each photo, for example to show the name of the nearest city. All of this happens on your iPhone, using a list of places built into the app. Photos, thumbnails and photo details are never uploaded to us or anyone else.
Your review progress (which photos you kept or put in the trash), settings, streaks, statistics and place names are stored only in the app’s storage on your iPhone. The app doesn’t sync them anywhere. Like all app data, they are part of your iPhone backup if you use iCloud Backup or back up to a computer. Deleting the app removes them from the iPhone.
The app uses three service providers. Each receives only the data below, processes it only to provide its service to us, under a data processing agreement, and must protect it at least as well as this policy describes.
| Provider | What it receives | Why | Can you turn it off? |
|---|---|---|---|
| Sentry Functional Software, Inc. Data stored in the EU (Germany). |
Crash and error reports: what went wrong, the app screens and buttons used just before it, app version, device model, iOS version, free memory and storage, language and time zone, and a random ID for the installation. Also a short note each time the app is opened, used to measure how often it crashes. No photos, screenshots or screen recordings. | Finding and fixing crashes. | Yes: Settings › Share Analytics. Takes effect the next time you open the app. |
| PostHog PostHog, Inc. |
Usage events with a random ID: the app being installed, updated, opened or closed; onboarding steps; reviews started, finished or left; how many photos were kept, deleted and how much space was freed; how many groups of similar photos were found; the subscription screen being shown or closed; purchases started, completed or failed; settings changed. Also app version, device model, iOS version, language and time zone. Never photo content, file names or locations. | Understanding which features are used, so we can improve them. | Yes: Settings › Share Analytics. Takes effect at once. |
| RevenueCat RevenueCat, Inc. (USA), together with Apple |
Your subscription status and purchase history (product, dates, price, country and currency, Apple transaction IDs), a random ID that RevenueCat creates for the app, and app, device and iOS version. Payments are made through Apple; we never see your card or Apple ID details. | Providing, checking and restoring Nixo Pro. | No, it’s needed for the subscription. If you don’t subscribe, it receives only the random ID and versions, to check whether you have a subscription. |
Like any internet connection, these services see your device’s IP address when the app connects to them. We have set Sentry and PostHog not to store it or use it to work out your location.
None of this data is linked to your name, email or Apple ID by us, and we never try to do so. We do not sell or “share” personal information (as those words are used in California law), we don’t show ads, and we don’t track you across other apps or websites.
Some providers are based in the United States, so data may be processed there. Where data from the EU, UK or Switzerland goes to another country, the providers rely on the EU–US Data Privacy Framework or the European Commission’s Standard Contractual Clauses.
Depending on where you live (for example under the GDPR in the EU and UK, or California law), you can ask to access, correct, delete or receive a copy of your data, to restrict its use, or object to it. Email support@nixo.photos; we reply within one month.
We won’t treat you differently for using these rights. If you are in the EU or UK and think we have mishandled your data, you can complain to your local data protection authority.
The app is not directed to children under 13 (or the age required in your country) and we don’t knowingly collect their personal information. If you believe a child has sent us data, email us and we will delete it.
All data the app sends is encrypted in transit (HTTPS). Access to the service providers’ dashboards is limited to us.
If we change this policy, we will post the new version here and update the date at the top. If a change affects how your data is used, we will also mention it in the app’s release notes.
