Domivka

Privacy Policy

Effective 27 October 2026

Domivka is a rental bookkeeping app for landlords. It is local-first: what you enter stays on your iPhone, and you can use the app without an account. Data reaches our servers in the EU (Frankfurt) only if you sign in and turn on cloud sync or the tenant portal, both part of Domivka Pro. We don't sell data, show ads or track you across apps.

1. Who we are

Domivka is run by Vladyslav Tsyndrin, an individual based in Lviv, Ukraine ("we", "us"). We are the controller of the data described in this policy, except where section 6 says otherwise. Contact: privacy@domivka.site.

2. Data on your device

Properties, units, tenants, leases, charges, payments, meter readings, expenses, documents, photos, inspection reports and settings are stored in the app's database on your iPhone. Without an account we don't receive any of it.

3. Account

An account is optional. You sign in with Apple. We receive a unique Apple user identifier, your email address (which may be an Apple private relay address) and, if you choose to share it, your name. Our hosting provider also keeps technical logs, such as IP address and sign-in times, to protect the service.

You can delete your account in Settings → Account. Deletion removes your account, every record synced to the server and all uploaded files, and revokes the app's Sign in with Apple access. Data on your iPhone stays there until you delete the app or the data.

4. Cloud sync and backup (Pro)

With cloud sync on, your records, photos and documents are copied to our database and private file storage so you can restore them and use several devices. Every record is tied to your account, and access rules on the server let only your account read it. Files are kept in a private bucket and are never public.

5. Tenant portal (Pro)

You can send a tenant a personal link to a web page at my.domivka.site. When you create or update a link, the app uploads a summary for that lease: your name as you want the tenant to see it, the amount due, recent charges and payments, meters and the payment details you entered. The server keeps only a hash of the link's secret token, not the token itself.

A tenant who opens the link sees that summary and can tell you they have paid or send a meter reading with an optional photo. Tenants don't create an account. A link stops working when you revoke it, when it expires (after one year) or when you delete your account.

6. Data about your tenants and other people

You may enter information about other people: tenants, guarantors and contacts, such as names, phone numbers, email addresses, messenger handles, ID document details and photos. For this data you are the controller and you decide why it's processed. Make sure you have a lawful basis, tell those people about it and keep only what you need. The ID document field is optional.

When this data is synced or shared through the tenant portal, we process it only on your behalf, as your processor, to provide the service. We don't use it for anything else and never combine data about the same person across different landlords.

7. Subscriptions

Domivka Pro is sold through the App Store. Apple processes the payment, and we never see your card details. We use RevenueCat to check whether your subscription is active. It receives an anonymous app user ID, your purchase history and basic device information (such as the iOS version and the country of your App Store account).

Where data leaves the European Economic Area, the transfer relies on the European Commission's standard contractual clauses or the EU–US Data Privacy Framework.

10. Legal bases

We also follow the Law of Ukraine "On Personal Data Protection", which provides similar grounds.

11. How long we keep data

12. Your rights

You can ask for access to your data, correction, deletion, restriction, a copy in a portable format and object to processing. Most of this you can do yourself: edit or delete records in the app, export everything in Settings and delete the account in Settings → Account. For anything else, write to privacy@domivka.site. We reply within one month.

Tenants and other people whose data a landlord entered should contact that landlord first. We will help the landlord respond.

You can also complain to a supervisory authority: in Ukraine, the Ukrainian Parliament Commissioner for Human Rights; in the EU, the authority in your country, for example the President of the Personal Data Protection Office (UODO) in Poland.

13. Security

Connections use HTTPS. The account session is kept in the iOS Keychain. On the server, each record is readable only by its owner's account, files are private, and tenant portal links are stored as hashes. You can also lock the app with Face ID or a passcode.

14. Children

Domivka is meant for adults managing rentals and isn't directed at children under 16.

15. Changes

If we change this policy, we will update the date above. If the change is significant, we will also tell you in the app before it takes effect.
