Contact
info@nostroapp.comWe reply within three business days, in Spanish. To report a problem, write from Nostro › Settings › Send feedback, which includes the app version and build in the subject, or email us with your Nostro version, iPhone model, iOS version, and a description of what happened.
Getting started
How do I install Nostro?
Nostro is distributed through the App Store. You can download it with the button on nostroapp.com or search for it by name in the App Store. An iPhone with iOS 18.4 or later and an active iCloud session are required.
Do both people need to install the app?
Yes. Nostro is designed for two people, each with their own iPhone. One person installs the app and creates the shared space; the other joins using an invitation link.
How do I pair with my partner?
From the start screen or Settings, the person who already has the app generates an invitation link and sends it however they prefer: WhatsApp, Messages, or AirDrop. The other person installs Nostro and then opens the link; the app opens and completes the pairing.
I opened the link and nothing happened
This usually means Nostro was not installed yet. Install it from the App Store and open the link again. If it was already installed, open the app once, close it, then open the link again.
Do I need to create an account?
No. Nostro uses your iPhone’s iCloud session. In Settings, under your name, check that iCloud is on and Nostro is allowed to use it.
The shared space
Can a third person join using the link?
No. The link stops working once the two people are linked. If someone else opens it, the app says the space is full.
My partner already had saved information and accepted my invitation
When someone accepts an invitation, their previous information is deleted so they can join the inviter’s space. The app warns them before continuing. If both people have saved information, we recommend that the person with more content send the invitation.
What I save does not appear on the other device
Check that both devices have an internet connection, an active iCloud session, and available iCloud storage. Synchronization usually finishes within seconds; if the app was closed, open it and wait a moment. If more than a minute passes, write to us with both iPhone models.
How do we unlink?
Use Settings in the app. Unlinking ends synchronization, and each person keeps the information already on their device. Pairing again creates a new space.
What happens to our information if the relationship ends?
Each person keeps the copy already on their device. Neither can delete information from the other person’s device without their confirmation: while linked, “Request to delete everything” asks the other person to approve it on their phone. If they decline or 24 hours pass, nothing is deleted. After unlinking, each person can use “Delete everything” on their own information.
What is saved when I share a TikTok, YouTube, or Instagram link?
Nostro saves the link and, when the post is public, its cover image, text, and the name of its creator. The video is not downloaded: opening it takes you to its original app or website. A reduced copy of the cover image stays on each iPhone. If the post is private or has been removed, the link is saved without a cover image and you can give it a name.
Your data
Where is information stored?
In each person’s iCloud account and in a zone shared by both. A reduced copy of each link’s cover image is also stored on the iPhone itself. Nostro does not operate its own servers and cannot access your content. See the Privacy Notice for details.
Does the app use my iCloud storage?
Yes. Photos, videos, and stories use storage. What the couple saves in the shared space counts against the iCloud quota of its creator; copies in “Your past stories” count against the quota of the person who posted each story, even if that person was invited.
Will I lose my information if I uninstall the app?
Information already saved in iCloud is restored when you reinstall with the same Apple Account. Anything not yet uploaded to iCloud, for example because there is no iCloud session, iCloud is restricted, or storage is full, is lost when you uninstall. To delete your data permanently, use “Delete everything” with no linked partner; with a partner, “Request to delete everything” requires the other person to confirm.
Can I export my photos?
Yes. With or without Nostro Pro, you can save an individual photo or video to Photos. Both options for exporting all photos to Photos require Nostro Pro. You can also export a PDF book: the full book with Nostro Pro or a preview without the subscription.
Troubleshooting
The app closes unexpectedly
Update Nostro to the latest version from the App Store and reopen it. If the problem continues, write from Nostro › Settings › Send feedback, which includes the app version, or to info@nostroapp.com with your Nostro version, iPhone model, and iOS version. Uninstalling the app is a last resort: only information already saved in iCloud can be restored.
How do I report a bug?
Write from Nostro › Settings › Send feedback, which includes the app version and build in the subject. You can also email info@nostroapp.com with your Nostro version, iPhone model, iOS version, and steps to reproduce the problem; attach a screenshot if possible.
A new version is available
If automatic updates are on, the App Store installs it for you; otherwise you can update it from your profile in the App Store. Updating preserves the data on your phone.
About Nostro
Is Nostro available on the App Store?
Yes. Nostro is on the App Store for iPhone with iOS 18.4 or later. We share news on Instagram at @nostroapp.
Does Nostro cost anything?
Nostro includes features at no cost and offers Nostro Pro, a monthly or yearly subscription purchased by one of the two people and available to both while they are linked. It is billed and canceled through the purchaser’s Apple Account and renews automatically unless automatic renewal is turned off at least 24 hours before the current term ends. Someone who has not previously used a Nostro Pro trial may receive one at no cost, lasting two weeks on the monthly plan or one month on the yearly plan, with only one trial per couple. When it ends, the subscription is charged unless canceled at least 24 hours beforehand. The price is shown in the app before you confirm the purchase, refunds are requested from Apple, and ending the subscription does not erase anything already saved. Details are in section 11 of the Terms and Conditions.
Will there be an Android version?
Nostro is an iPhone app. There are currently no plans for an Android version.
How do I stop using Nostro?
You can uninstall the app. If you have Nostro Pro, cancel the subscription in your Apple Account settings, since uninstalling the app does not cancel it. Only what was already saved in iCloud remains there; anything not yet uploaded is lost when you uninstall. To delete information permanently, use “Delete everything” with no linked partner or, with a partner, “Request to delete everything” before uninstalling.
