Spark Privacy Policy

Effective date: 29 July 2026

Version 1.0

Spark is an app for couples. Its heart is a daily photo moment you share with your partner, surrounded by things like a private gallery, location sharing, anniversaries, a bucket list, date planning, and small games you play together.

Because Spark is built for two people who trust each other, we take the data you put into it seriously. This policy explains, in plain language, what we collect, why, who else touches it, what your partner can see, how long we keep it, and the rights you have. If anything here is unclear, please email us — the contact is in the first section.

1. Who we are

Spark is operated by Nikodem Zelenak as the controller of your personal data — an individual based in Slovakia, in the European Union, who runs Spark independently; there is no company behind it yet. Throughout this policy, "we" and "us" mean the operator.

You can reach us about anything in this policy, or to exercise any of your rights, at:

privacy@mysparks.app

Because we are established in Slovakia, our lead supervisory authority is the Slovak data protection authority, the Úrad na ochranu osobných údajov Slovenskej republiky (Office for Personal Data Protection of the Slovak Republic). You always have the right to contact them, or your own local authority, if you have a concern (see Section 7).

This policy covers the Spark mobile app and this website (www.mysparks.app).

2. What we collect

We collect only what Spark needs to work, plus a little that helps us improve it (and that only with your permission). Here is everything, grouped by what it is:

Your account. Your email address and password, or — if you choose to sign in that way — your identity from Sign in with Google or Sign in with Apple. This is how you log in.

Your profile. Your username, your birthday, an optional phone number, and an avatar image if you add one. When you pair with a partner, we also handle an invite code that links the two of you.

Your relationship details. Things you tell Spark about your relationship — such as important dates, shared goals, habits you're building together, and what you want to focus on. We also store the fact that you are paired with your partner and your time zone. Because information about your relationship can reveal or suggest intimate details about you, we treat it with extra care (see Section 3).

Your daily photo moments. When you capture a daily Spark, we store the photos (typically a front-camera and a back-camera image), any caption you add, and an optional location label you choose to attach.

Your location — including in the background — when Together Map sharing is on. If you turn on location sharing (Together Map), we collect your precise location so your partner can see where you are. When sharing is on, this can include location updates while the app is in the background. We keep only your latest point — each update overwrites the one before it, so there is no location history. Turning on Ghost Mode pauses sharing.

Anniversaries and milestones. The dates and milestones you add.

"Thinking of you" nudges and located hearts. When you tap "thinking of you," we record the nudge — who sent it and when — so your partner still sees it even if the push notification never arrives, and the time of your latest one can appear on their home-screen widget. Unless you're in Ghost Mode, the nudge also carries the precise location you sent it from, so a heart lands on your partner's Together Map at that spot for them to collect — this is location-attached content. (In Ghost Mode we don't attach your live position; the heart is pinned at your last shared location — the frozen spot your partner's map already shows — or arrives without a place if you've never shared one.) Unlike your live location, collected hearts leave a lasting "thought trail" and add up over time into a shared keepsake, so we keep them (see Section 6); collecting them earns the two of you a little XP.

Your bucket list. The items you add, along with any notes, photos, and addresses attached to them - and, if you schedule one, the date you plan to do it. If you tap "add to calendar," Spark writes that one event into your device calendar right on your phone. To do that it only looks up which of your calendars it can write to - it never reads your events, and nothing about your calendar is sent to us.

Date-planner inputs. When you use the date planner, we use your location and the preferences you enter to find date ideas nearby (this involves the processors named in Section 4).

Games — including Would You Rather answers. When you play the built-in minigames (Trivia, Draw Battle, Love Golf, Would You Rather, Battleship), we store your answers, moves, and scores. This includes your Would You Rather answers, which can be personal.

Private notes. Notes you write for yourself in the app (for example, Trivia notes) that are visible only to you.

Drawings. When you draw, we store the finished image and the stroke-by-stroke replay data (the sequence of strokes that lets a drawing play back).

In-app activity and rewards. As you use Spark you earn experience points (XP); we log the in-app actions that award them.

Push tokens. To send you notifications, we store the push token for your device (including the token used for live activities). Your partner's app can read your push token so it can notify you.

On your device. Some data lives on your phone rather than on our servers — for example your login session (kept in secure storage), a copy of your partner's details and last location so features and home-screen widgets work, and widget data shared with the operating system.

Device info and usage analytics — only with your consent. If, and only if, you opt in, we collect first-party analytics about how the app is used: which features you use and how often, session counts and length, which screens you visit, which notifications you tap, and where people drop off in sign-up and pairing — plus technical context like app version, operating system, device model, coarse country, and a random, app-generated identifier. Analytics answers "how many, how often, which feature, how long"never the content of your photos, drawings, messages, notes, captions, answers, precise location, or your or your partner's identity. If you don't opt in, we collect no analytics.

3. Why we use your data (legal bases)

Under the GDPR we must have a lawful basis for using your data. Here is ours, by purpose:

Heightened care for relationship data. Information about your relationship, your Would You Rather answers, and the simple fact that you are paired with a partner can suggest intimate aspects of your life. We treat this information with particular care, keep it scoped to you and your partner, and do not use it for advertising or profiling.

4. Who else processes your data

We keep Spark lean, but a few trusted service providers ("processors") help us run it. They act on our instructions, and we share with them only what each one needs.

Processor What they do for Spark What they receive
Supabase Hosting, database, and file storage (our core backend) — region: United Kingdom (London) The data described in Section 2 that lives on our servers
Google Sign in with Google; map tiles on Android Sign-in identity if you use it; map view data when you use maps on Android
Apple Sign in with Apple; push notification delivery (APNs); map tiles on iOS Sign-in identity if you use it; push tokens/notifications; map view data when you use maps on iOS
Expo Delivery of push notifications Push tokens and notification content routed to your device
Geoapify Date-planner ideas and map images The coordinates and search terms needed to find nearby places
Tripadvisor Photos of suggested venues in the date planner Only the coordinates of the venue being shown — no identity, and never your own location
Unsplash A small number of decorative stock images shown in the app Standard web-request data (such as your IP address) when the image loads

When you tap an external link in Spark (for example, to a social media profile such as Instagram), that takes you to a third-party site governed by its own privacy policy; those sites are not processors for us.

We do not sell your data. We do not show ads. We use no advertising or tracking SDKs.

5. What your partner sees

Spark is a shared app, so honesty here matters. Once you are paired, your partner can see:

Some profile details are visible to your partner through the app — keep that in mind when adding a phone number or birthday.

Unpairing. If you unpair, sharing between you stops and the couple-only data that existed just because you were together - such as games and your bucket list - is deleted.

When one of you deletes their account. When you delete your Spark account, we remove your profile, your logins, and your side of Spark. One thing we keep, on purpose: the photo memories you made together stay with your partner — because they're theirs too, and deleting your account shouldn't erase their memories. Your name and details come off them. Everything else tied just to the two of you - your games, XP, bucket list, anniversaries, and drawings - is deleted. Within 30 days you can undo (until then, access is locked). Want specific photos — or all of them — gone from your partner's side as well? Just email privacy@mysparks.app and we'll take care of it; we honor these requests, especially for sensitive photos. And if you have no partner, or you're the last one to leave, everything — including the shared photos — is deleted.

6. How long we keep it

We keep data only as long as we need it. Here is the plain version:

Data How long we keep it
Your account identity — profile, logins, and personal details Deleted when you delete your account, after the 30-day undo window below
Shared photo memories — daily Spark photos, captions, and the couple gallery Stay with your remaining partner (as their memories, with your name and details removed) until they delete them or delete their own account. If you have no partner or are the last to leave, they are deleted with everything else. You can ask us to remove specific photos, or all of them, at any time (privacy@mysparks.app)
Deletion undo window 30 days after you delete your account, during which access is locked and you can still undo; after it, the deletion is permanent
Finished or abandoned minigames Purged after roughly 12 hours (aggregate win counts are kept until you delete your account)
Raw analytics events 13 months, after which they are retained only as pseudonymised, aggregated statistics (your identifiable analytics are deleted when you delete your account)
Soft-deleted bucket-list items Hidden from you and your partner as soon as you delete them, and permanently removed shortly after (and in all cases when you delete your account)
Location Only your latest point — each update overwrites the previous one
"Thinking of you" nudges and located hearts Kept on purpose as a shared keepsake — they build up over time with no automatic cleanup, and are removed when you delete your account or the couple's shared data is deleted
Push tokens Until you sign out or delete your account
Billing and subscription records Kept for about 10 years, because tax and accounting law requires it — metadata only (who paid what, and when), never your photos or content
Fraud-prevention token A minimal marker kept 6–12 months to stop a banned user from evading the ban — no photos or content
Backups Age out on a fixed rotation; data you deleted is put beyond use in any backup that still holds it and is never restored
Anonymised aggregate statistics May be kept indefinitely — but only in a form that carries no per-user or per-couple identifiers, so it can no longer be linked back to you

7. Your rights

You are in control of your data. You can exercise all of these rights, and we will not charge you or treat you differently for doing so.

Everyone gets these rights, worldwide. We honor these same rights for all Spark users regardless of where you live, including users in California and elsewhere in the United States.

8. International transfers

Our servers are in the United Kingdom: the data described in Section 2 that lives on our backend is hosted by Supabase in London. Moving your data from the EU to the UK is fine because the European Commission has decided that the United Kingdom provides an adequate level of data protection — its adequacy decision for the United Kingdom — so your data is protected there to essentially the same standard as it is in the EU.

Some of the other providers in Section 4 are US companies — Apple, Google, Expo, Tripadvisor, and Unsplash — and may process some of your data in the United States. Where that happens, we rely on the safeguards recognized under the GDPR: the EU-U.S. Data Privacy Framework and/or the European Commission's Standard Contractual Clauses (SCCs). Geoapify processes your data in Germany, within the EU.

You can contact us at privacy@mysparks.app for more information about any of these safeguards.

9. Security

We take reasonable steps to protect your data. Connections between the app and our servers are encrypted in transit (HTTPS/TLS), and access to your data is scoped so that, in the normal operation of the app, it is limited to you and your paired partner through per-couple access controls.

No app or online service can promise perfect security, and we do not. We are continuing to strengthen how your content is stored and protected, and we will update this policy as we do. If we ever become aware of a data breach that affects you, we will act on our legal obligations to notify the relevant authority and, where required, you.

10. Children

Spark is for people aged 16 and over. It is not intended for children under 16, and we do not knowingly collect data from them. If we learn that an account belongs to someone under 16, we will delete that account and its data.

11. Changes to this policy

This policy is version 1.0, effective 29 July 2026.

If we make material changes — for example, collecting something new or using a new processor — we will announce the change in the app before it takes effect, and update the effective date above. Your continued use of Spark after a change means you accept the updated policy.
