Privacy policy.

The short version: One Follower has no account and no server. Nothing you do in One Follower is sent to us or to anyone else. One Follower collects no data.

Effective 13 November 2026

One Follower is an app that shows the photos and videos already on your phone as a full-screen feed. This policy covers the One Follower app on iPhone and on Android, and this website.

1. Who is responsible

One Follower is published by Rodrigo Luque, based in Spain. Contact for anything about privacy: hello@onefollower.app.

2. What One Follower reads on your phone

With your permission, One Follower reads the photos and videos in your phone’s gallery, and for each one its date, file name, pixel size, length (for videos) and type (photo, video, Live Photo, screenshot). One Follower uses this only to show them to you on your phone and to decide the order.

One Follower does not read where a photo was taken. It does not use the camera, the microphone, your contacts or your location.

You choose how much One Follower can see: everything, only the photos you pick (where your phone offers that), or nothing. You can change this at any time in your phone’s Settings.

3. What One Follower collects

Nothing. One Follower has no account and no sign-up. One Follower has no server. Your photos, your videos and everything you do in One Follower are not sent to us or to any other company. One Follower has no analytics, no crash reporting, no advertising and no tracking, and it reads no advertising identifier.

4. What One Follower saves on your phone

One Follower keeps a small file inside the app on your phone. It holds:

• the photos and videos you loved, and when;
• your private notes, with the date and file name of the photo or video each note belongs to;
• the list of what you hid from your feed;
• which photos and videos you have looked at in One Follower, when you last saw each one and how many times;
• what One Follower has learned from that to order your feed: a score for each item you reacted to and for each month of your gallery, built from what you love, linger on, replay, open, share, write about, skip or hide;
• your settings: the switches, the reminder time, the size of your gallery and a count of how many items you have looked at.

One Follower does not keep copies of your photos or videos. It shows them straight from your gallery. Temporary files are the only exception. They are described in section 6.

5. Your phone’s own backup, and your own cloud

If your phone backs itself up (iCloud Backup on iPhone, Google backup on Android), the file described in section 4 is part of that backup, under your own Apple or Google account. That is done by your phone, not by One Follower. We cannot see it.

If you use iCloud Photos or a similar service, your photos are already stored there by your phone, with or without One Follower. When a photo’s original is kept in iCloud and not on the iPhone, the iPhone may download it from your iCloud so that One Follower can show it. That happens between your phone and Apple.

6. Sharing, and temporary files

One Follower shares a photo or video only when you press Share. One Follower’s own share sheet opens. It shows the photo or video, its date, a button for each app that can be opened directly with the file attached, and “More apps”.

A button opens that app with the photo or video attached. If the app cannot take it that way, your phone’s own share sheet opens instead. Nothing is sent until you press send there. “More apps” opens your phone’s own share sheet, where you pick where it goes. If no app has a button on your phone, your phone’s own share sheet opens straight away. From there, the policy of the app or person you chose applies.

To decide which buttons to show, One Follower on Android asks the phone whether WhatsApp and Telegram are installed, and whether the phone can send messages. The answer is used only to draw the buttons. It is held in memory while One Follower is open. It is not saved and not sent anywhere. On iPhone the only button is Messages, and One Follower asks only whether the iPhone can send messages.

To hand the file over, One Follower on Android makes a temporary copy inside the app. Android does not tell One Follower when the other app has finished reading it, so the copy is kept for at least one day. One Follower deletes copies that are more than a day old the next time you share something or the next time it starts.

On iPhone, One Follower hands over the file from your gallery as it is. For a slow-motion video, the system first writes a normal video to a temporary file inside the app, and that file is handed over. It stays in the app’s temporary folder until the iPhone clears it.

A file that is handed over can hold the place where the photo or video was taken, if your phone saved it there. One Follower does not read it, but the app or person you send the file to receives it. That is so on iPhone. On Android, One Follower does not have the permission that Android requires before it gives an app the place stored in a photo, and Android states that it then leaves the place out of the photo. In videos, the copy can hold the place.

On iPhone, to play the moving part of a Live Photo, the system writes that clip to a temporary file. One Follower plays it and sends it nowhere.

7. Deleting from your phone

One Follower deletes a photo or video from your phone only when you choose “Delete from phone”. Your phone asks you to confirm first. When an item is deleted, One Follower also removes what it had saved about it.

8. Reminders

One Follower can send you one reminder a day. It is off until you turn it on. The reminder is scheduled on your phone. One Follower uses no push service and no server for it.

9. Permissions on Android

One Follower asks for access to photos and videos and, if you turn the reminder on, for permission to show notifications. The Android version also lists the network permission, because the parts it is built with (the picture and video players) declare it. One Follower does not use it to send anything.

10. Other companies

None. No other company receives data from One Follower, so there is nobody to list here.

11. Keeping it safe

Everything One Follower saves is kept in the app’s private storage on your phone, protected by your phone’s lock and its own encryption. It may also be in your phone’s own backup (section 5). One Follower adds no encryption of its own. One Follower sends nothing anywhere, so nothing can be intercepted on the way.

12. How long it is kept, and how to erase it

What One Follower saves stays on your phone until you remove it:

• In One Follower, open Settings and choose “Erase One Follower data”. This clears your loves, your notes, the hidden list, what you have looked at and what One Follower learned from it. Your settings stay. Your photos and videos are not touched.
• Or delete the app. That removes everything One Follower saved. A copy may remain in your phone’s own backup until that backup is replaced.

You can take away One Follower’s access to your photos at any time in your phone’s Settings.

One Follower gives us no data about you, so there is nothing for us to send you, correct or delete. If you have written to us by email, ask and we will delete your message. For any question, write to hello@onefollower.app. If you live in the European Union you may also complain to your data protection authority. In Spain that is the Agencia Española de Protección de Datos (www.aepd.es).

13. Children

One Follower is not made for children. It collects nothing from anyone, whatever their age.

14. This website

onefollower.app has no accounts, no analytics and no form that sends anything, and the site sets no cookies of its own. Its fonts and pictures are served from onefollower.app itself, so opening it calls nobody but the host named below. The demonstration on the home page (the heart, the note, the share button) runs in your browser: what you type there is not saved or sent.

The site is hosted by Vercel. Like any web host, it handles the technical data of each visit, such as the IP address, to deliver the page and to protect it from abuse.

If you write to us by email, we use your address and your message only to answer you.

15. Changes

If this policy changes, the new text and its date appear on this page. If a later version of One Follower ever adds an account, analytics or advertising, this page will say so before that version is released.
